NVIDIA Releases GeForce 378.72 Hotfix (Bonus: a Discussion)

Just a couple of days after publishing 378.66, NVIDIA released GeForce 378.72 Hotfix drivers. This fixes a bug encoding video in Steam’s In-Home Streaming, and it also fixes PhysX not being enabled on the GPU under certain conditions. Normally, hotfix drivers solve large-enough issues that were introduced with the previous release. This time, as far as I can tell, is a little different, though. Instead, these fixes seem to be intended for 378.66 but, for one reason or another, couldn’t be integrated and tested in time for the driver to be available for the game launches.

This is an interesting effect of the Game Ready program. There is value in having a graphics driver available on the same day (or early) as a major game releases, so that people can enjoy the title as soon as it is available. There is also value in having as many fixes as the vendor can provide. These conditions oppose each other to some extent.

From a user standpoint, driver updates are cumulative, so they are able to skip a driver or two if they are not affected by any given issue. AMD has taken up a similar structure, some times releasing three or four drivers in a month with only, like, one of them being WHQL certified. For these reasons, I tend to lean on the side of “release ‘em as you got them”. Still, I can see people feeling a little uneasy about a driver being released incomplete to hit a due-date.

But, again, that due-date has value.

It’s interesting. I’m personally glad that AMD and NVIDIA are on a rapid-release schedule, but I can see where complaints could arise. What’s your opinion?

NVIDIA Releases GeForce 378.66 Drivers with New Features

Tagged: opencl 2.0, opencl, nvidia, graphics drivers

While the headline of the GeForce 378.66 graphics driver release is support for For Honor, Halo Wars 2, and Sniper Elite 4, NVIDIA has snuck something major into the 378 branch: OpenCL 2.0 is now available for evaluation. (I double-checked 378.49 release notes and confirmed that this is new to 378.66.)

OpenCL 2.0 support is not complete yet, but at least NVIDIA is now clearly intending to roll it out to end-users. Among other benefits, OpenCL 2.0 allows kernels (think shaders) to, without the host intervening, enqueue work onto the GPU. This saves one (or more) round-trips to the CPU, especially in workloads where you don’t know which kernel will be required until you see the results of the previous run, like recursive sorting algorithms.

So yeah, that’s good, albeit you usually see big changes at the start of version branches.

Another major addition is Video SDK 8.0. This version allows 10- and 12-bit decoding of VP9 and HEVC video. So... yeah. Applications that want to accelerate video encoding or decoding can now hook up to NVIDIA GPUs for more codecs and features.

NVIDIA’s GeForce 378.66 drivers are available now.

AMD Releases Radeon Software Crimson ReLive 17.2.1

Subject: Graphics Cards | February 14, 2017 - 10:57 PM |
Tagged: amd, graphics drivers

Just in time for For Honor and Sniper Elite 4, AMD has released a new set of graphics drivers, Radeon Software Crimson ReLive 17.2.1, that target these games. The performance improvements that they quote are in the 4-5% range, when compared to their previous driver on the RX 480, which would be equivalent to saving a whole millisecond per frame at 60 FPS. (This is just for mathematical reference; I don’t know what performance users should expect with an RX 480.)

Beyond driver overhead improvements, you will now be able to utilize multiple GPUs in CrossFire (for DirectX 11) on both titles.

Also, several issues have been fixed with this version. If you have a FreeSync monitor, and some games fail to activate variable refresh mode, then this driver might solve this problem for you. Scrubbing through some videos (DXVA H.264) should no longer cause visible corruption. A couple applications, like GRID and DayZ, should no longer crash under certain situations. You get the idea.

If you have an AMD GPU on Windows, pick up these drivers from their support page.

NVIDIA Releases Vulkan Developer 376.80 Beta Drivers

Subject: Graphics Cards | February 3, 2017 - 10:58 PM |
Tagged: nvidia, graphics drivers, vulkan

On February 1st, NVIDIA released a new developer beta driver, which fixes a couple of issues with their Vulkan API implementation. Unlike what some sites have been reporting, you should not download it to play games that use the Vulkan API, like DOOM. In short, it is designed for developers, not end-users. The goal is to provide correct results when software interacts with the driver, not the best gaming performance or anything like that.

khronos-2016-vulkanlogo2.png

In a little more detail, it looks like 376.80 implements the Vulkan 1.0.39.1 SDK. This update addresses two issues with accessing devices and extensions, under certain conditions, when using the 1.0.39.0 SDK. 1.0.39.0 was released on January 23rd, and thus it will not even be a part of current video games. Even worse, it, like most graphics drivers for software developers, is based on the old, GeForce 376 branch, so it won’t even have NVIDIA’s most recent fixes and optimizations. NVIDIA does this so they can add or change the features that Vulkan developers require without needing to roll-in patches every time they make a "Game Ready" optimization or something. There is no reason to use this driver unless you are developing Vulkan applications, and you want to try out the new extensions. It will eventually make it to end users... when it's time.

If you are wishing to develop software using Vulkan’s bleeding-edge features, then check out NVIDIA’s developer portal to pick up the latest drivers. Basically everyone else should use 378.49 or its 378.57 hotfix.

Tagged: graphics drivers, amd

A few days ago, AMD released their second graphics drivers of January 2017: Radeon Software Crimson ReLive 17.1.2. The main goal of these drivers are to support the early access of Conan Exiles as well as tomorrow’s closed beta for Tom Clancy’s Ghost Recon Wildlands. Optimization that AMD has been working on prior to release, for either game, are targeted at this version.

Beyond game-specific optimizations, a handful of bugs are also fixed, ranging from crashes to rendering artifacts. There was also an issue with configuring WattMan on a system that has multiple monitors, where the memory clock would drop or bounce around. There is driver also has a bunch of known issues, including a couple of hangs and crashes under certain situations.

Radeon Software Crimson ReLive Edition 17.1.2 is available at AMD’s website.

NVIDIA Release GeForce 378.57 Hotfix Drivers

Tagged: nvidia, graphics drivers

If you were having issues with Minecraft on NVIDIA’s recent 378.49 drivers, then you probably want to try out their latest hotfix. This version, numbered 378.57, will not be pushed down GeForce Experience, so you will need to grab them from NVIDIA’s customer support page.

Beyond Minecraft, this also fixes an issue with “debug mode”. For some Pascal-based graphics cards, the option in NVIDIA Control Panel > Help > Debug Mode might be on by default. This option will reduce factory-overclocked GPUs down to NVIDIA’s reference speeds, which is useful to eliminate stability issues in testing, but pointlessly slow if you’re already stable. I mean, you bought the factory overclock, right? I’m guessing someone at NVIDIA used it to test 378.49 during its development, fixed an issue, and accidentally commit the config file with the rest of the fix. Either way, someone caught it, and it’s now fixed, even though you should be able to just untick it if you have a factory-overclocked GPU.

NVIDIA Releases GeForce 378.49 Drivers

Tagged: nvidia, graphics drivers

Update: There are multiple issues being raised in our comments, including a Steam post by Sam Lantinga (Valve) about this driver breaking In-Home Streaming. Other complaints include certain applications crashing and hardware acceleration issues.

Original Post Below

Now that the holidays are over, we’re ready for the late-Winter rush of “AAA” video games. Three of them, Resident Evil VII, the early access of Conan Exiles, and the closed beta of For Honor, are targeted by NVIDIA’s GeForce 378.49 Game Ready drivers. Unless we get a non-Game Ready driver in the interim, I am guessing that this will cover us until mid-February, before the full release of For Honor, alongside Sniper Elite 4 and followed by Halo Wars 2 on the next week.

Beyond game-specific updates, the 378-branch of drivers includes a bunch of SLI profiles, including Battlefield 1. It also paves the way for GTX 1050- and GTX 1050 Ti-based notebooks; this is their launch driver whenever OEMs begin to ship the laptops they announced at CES.

This release also contains a bunch of bug fixes (pdf), including a reboot bug with Wargames: Red Dragon and TDR (driver time-out) with Windows 10 Anniversary Update. I haven’t experienced any of these, but it’s good to be fixed regardless.

You can pick up the new drivers from their website if, you know, GeForce Experience hasn’t already notified you.

NVIDIA Releases GeForce 376.48 Hotfix Drivers

Tagged: nvidia, graphics drivers

The latest hotfix drivers from NVIDIA, 376.48, address five issues, some of which were long-standing complaints. The headlining bug is apparently a workaround for an issue in Folding@Home, until the application patches the root issue on its end. Prior to this, users needed to stick on 373.06 in order to successfully complete a Folding@Home run, avoiding all drivers since mid-October.

Other fixes include rendering artifacts in Just Cause 3, flickering and crashes in Battlefield 1, and rendering issues in Wargame: Red Dragon. These drivers, like all hotfix drivers, will not be pushed by GeForce Experience. You will need to download them from NVIDIA’s support page.

AMD Releases Radeon Software Crimson ReLive 16.12.2

Tagged: graphics drivers, amd

Last week, AMD came down to the PC Perspective offices to show off their new graphics drivers, which introduced optional game capture software (and it doesn’t require a login to operate). This week, they are publishing a new version of it, Radeon Software Crimson ReLive Edition 16.12.2, which fixes a huge list of issues.

amd-2016-crimson-relive-logo.png

While most of these problem were minor, the headlining fix could have been annoying for FreeSync users (until this update fixed it, of course). It turns out that, when using FreeSync with a borderless fullscreen application, and another monitor has an active window, such as a video in YouTube, the user would experience performance issues in the FreeSync application (unless all of these other windows were minimized). This sounds like a lot of steps, but you could imagine how many people have a YouTube or Twitch stream running while playing a semi-casual game. Also, those types of games lend themselves well to being run in borderless window mode, too, so you can easily alt-tab to the other monitors, exacerbating the issue. Regardless, it’s fixed now.

Other fixed issues involve mouse pointer corruption with an RX 480 and multi-GPU issues in Battlefield 1. You can download them at AMD's website.

NVIDIA Releases GeForce 376.33 Drivers

Subject: General Tech | December 14, 2016 - 10:07 PM |
Tagged: nvidia, graphics drivers

While they’re not really promoting this release, such as with a blog post on the GeForce website, NVIDIA has just released their 376.33 WHQL drivers. This one is not associated with any specific game release, so it seems like this is more of a maintenance release, working on bugs rather than application-dependent optimizations. The release notes specifically mention several security improvements, so I would assume they’re going back through previous changes and looking at things like video memory management, which might also lead to overall performance and stability enhancements.

As for the long-running Folding@Home bug affecting some of our readers, it turns out that the cause was a bug in the application that just happened to work until NVIDIA applied a fix on their end. This reminds me of when I was working on an OpenCL-based software renderer. At one point, I started crashing when executing on the Intel CPU, but not on either GPU (Intel HD 4600 or NVIDIA GTX 670). I later found out that it was an out-of-bounds access in my code, when a render group slightly bled off the side of the render buffer, which the GPU drivers silently compensated for. It looked like Intel’s CPU driver had a bug, but, really, it was just the only one that didn’t work around my bug.

Despite this, NVIDIA is planning on releasing a workaround for Folding@Home in a hotfix driver, until the organization can patch the issue on their own. This driver is not the one, though.
