NVIDIA 387.34 vs. Linux 4.15 + Mesa 17.4-dev Radeon OpenGL/Vulkan Performance
BioShock Infinite was first up, which received many RadeonSI optimizations this year, and goes to show with the strong performance against the NVIDIA graphics cards in this OpenGL game.
But with Counter-Strike: Global Offensive it's still not performing too well with RadeonSI Git with the RX Vega cards performing just above the GeForce GTX 1070 speeds, but at least the RX 580 is outperforming the GTX 1060.
Deus Ex: Mankind Divided still could use better optimizations, particularly for Vega. The RX 580 is faster than the GTX 1060, but the RX Vega cards are basically only in line with the R9 Fury performance that is around GTX 1070 speeds.
With ultra quality settings, at least the RX Vega cards are coming out a little faster than the R9 Fury, but not as competitive as they should be for the hardware's abilities.
