Proton Slows RTX 4090, 4080 on Linux by 10% vs. Windows 11 Gaming Benchmarks
Just lately Phoronix published an article It covers the efficiency variations between Nvidia’s high graphics playing cards, the GeForce RTX 4090 and RTX 4080, and Home windows 11 and Linux Ubuntu. For gaming, each GPUs had been discovered to be 10% slower on Linux than Home windows 11 when gaming with non-native Linux gaming functions. . Naturally, each working methods work very equally.
For testing, Phoronix used a check rig consisting of the all-new Ryzen 7 7800X3D. Examined video games and benchmarking apps embody: cyberpunk 2077, shooter 3, Unigine Paradise 4And Unigine Superposition. cyberpunk And hitman Whereas operating in Steam’s Proton compatibility layer, Unigine apps had devoted native apps for Linux.
Inside cyberpunk 2077, At 1440P Extremely settings, the RTX 4090 was 13% slower on Linux than Home windows 11 Professional. The RTX 4080 labored equally and was 15% slower on Linux Ubuntu than Home windows 11.
At 1440P excessive settings, the hole begins to shut for the RTX 4090, the place the Linux OS is barely 5% slower than Home windows 11 Professional. Unusually, when testing at medium graphics settings, the RTX 4090’s body charges do not come near excessive settings for unknown causes.
At 1440P excessive, the RTX 4080 didn’t behave the identical because the RTX 4090. As with extremely settings, there’s additionally a 15% efficiency hole. Make sure to try the Phoronix article for particulars on 4K outcomes. However general, 4K outcomes share related conduct with 1440P outcomes.
shooter 3 yielded fascinating outcomes. The 1440P outcomes had been a lot nearer collectively between the 2 working methods, however at 4K the sport confirmed a a lot wider efficiency distinction between Linux and Home windows. At 1440P Extremely settings, the RTX 4090 and 4080 had a 4% to five% efficiency distinction between Linux and Home windows. At 4K Extremely settings, the body price distinction goes as much as 14% and 15% respectively.
Not surprisingly, Unigine Paradise And superposition the outcomes had been mainly the identical between each working methods, with each the RTX 4090 and 4080, as each apps have native apps for Home windows and Linux. At finest, there was a 1.5% distinction between each benchmark apps at 1440P and 4K.
Steam’s Proton compatibility layer is the primary problem stopping Nvidia’s 40-series GPUs from reaching Home windows-like efficiency on Linux. Nonetheless, that is to be anticipated as Proton’s API translation from DX to Vulkan requires further processing overhead. Both means, the ten% efficiency penalty (on common) is not that vital, and contemplating how highly effective these GPUs are, 90% of an RTX 4090 or 4080 nonetheless delivers a superb 4K or 1440P gaming expertise. .
