RadeonSI NIR Benchmarks Show Great Progress With Mesa 20.0
In the aging BioShock Infinite Linux game port, switching to NIR provided slight performance gains for the RX 590 and RX Vega 56 but with lower minimum frame-rates. With the new Navi/GFX10 graphics, using NIR caused a minor performance regression.
With Deus Ex: Mankind Divided as one of the most demanding OpenGL Linux-native games, the NIR impact varied from no change in run-time performance to slightly lower performance.
DiRT Rally meanwhile provided a frame or two advantage with the NIR code path on RadeonSI Mesa 20.0.
