AMD Radeon Vega Frontier Edition CrossFire Testing
Dirt Rally (DirectX 11)
DiRT Rally is the most authentic, challenging and thrilling rally game ever made, road-tested over 80 million miles by the DiRT community. It captures the essence of what makes rally unique like no other game: that white knuckle feeling of racing on the edge; trying to remain in control of your emotions as you hurtle along dangerous, undulating roads at breakneck speed, aiming to squeeze everything out of your car whilst knowing that one crash could irreparably harm your stage time.
It’s the ultimate test of a driver’s skill, and the ultimate in high risk, high reward gameplay.

Looking purely at average frame rate, the CrossFire solution sees 20% scaling at 2560x1440 but 54% scaling at 4K. Neither of those results is particularly amazing, and when we add in the higher than desired frame time variance we see, especially at 4K where we cross 2.5ms at about the 55th percentile (meaning 45% of the frame times have more the 2.5ms of average variance). At 4K this does bring the dual Vega FE in line with the average frame rate of the GTX 1080 Ti, though with a less smooth frame rate.
