Since the launch of Cyberpunk 2077, AMD CPU users have been finding that their chips are not being fully utilized, especially when it comes to SMT multithreading.
This issue has been around since the game’s release, and while CDProjektRed says the issue has been addressed in the HotFix 1.05 patch, PCGamesHardware testing found that this does not appear to be the case.
Testing found that the Cyberpunk 2077 HotFix 1.05 patch addresses SMT / thread utilization on AMD Ryzen CPUs, but mainly for 4-core and 6-core SKUs (Intel CPUs are not affected).
According to developers, the 8-core, 12-core, and 16-core chips operate normally, but benchmarks indicate that there is still thread underutilization, which can lead to PC performance degradation.
Existing developers have found that it’s actually quite simple to fix this issue, as you can manually replace the hex value “75 2D 33 C9 B8 01 00 00 00 0F A2 8B C8 C1 F9 08” in Cyberpunk 2077 with “EB 2D 33 C9 B8 01 00 00 00 0F A2 8B C8 C1 F9 08” using a simple HEX editor. “EB 2D 33 C9 B8 01 00 00 00 0F A2 8B C8 C1 F9 08”.
PCGameshardware testing results show a 27% performance increase after applying the new unofficial patch.
With the AMD Ryzen 7 7800X3D CPU, the average FPS of this CPU increased from 108.3 FPS to 137.9 FPS. This shows that this game still has major issues with the optimization of the 8-core CPU.
A few days ago, Cyberpunk 2077 version update 1.63 is now available, which includes various gameplay and mission fixes. the PC version improves DLSS frame generation performance on AMD CPUs.
