Cyberpunk 2077's 1.05 patch addresses the game's Ryzen performance issues | OC3D News (overclock3d.net)
 
CD Projekt Red has released patch 1.05 for Cyberpunk 2077, optimising the game for Ryzen-powered PC while also removing the game's AVX requirements. On top of this, patch 1.05 implements a large number of bug fixes and removes the game's "memory_pool_budgets.csv", a file which is not connected to the retail version of Cyberpunk 2077, despite recent rumours. Cyberpunk 2077's Ryzen CPU optimisations only impact users of 4-core and 6-core processors, as 8-core and higher core count Ryzen processors were already working as intended. These changes were implemented in co-operation with AMD. 

With Cybererpunk's patch 1.05, PC and console games should have a more stable, less buggy experience, though it is likely that many of Cyberpunk 2077's bugs have not been addressed. Full patch notes for Cyberpunk 2077 patch 1.05 are available below:

Performance & Stability

Miscellaneous

• Offscreen explosions make noise now.

 
PC-specific

• [AMD SMT] Optimized default core/thread utilization for 4-core and 6-core AMD Ryzen(tm) processors. 8-core, 12-core and 16-core processors remain unchanged and behaving as intended. This change was implemented in cooperation with AMD and based on tests on both sides indicating that performance improvement occurs only on CPUs with 6 cores and less.
• Fixed an issue with the way Raw Input is collected.
• Removed the use of AVX instruction set thus fixing crashes occurring at the end of the Prologue on processors not supporting AVX.
• Removed debug console to prevent functions that could lead to crashes or blocked quests. This doesn't mean we don't want to support the modding community. Stay tuned for more info on that.
• Ray traced reflections should no longer seem too bright in comparison to the environment.
• Fixed an issue with Steam Overlay crash on game shutdown.
• Removed the memory_pool_budgets.csv file. which was not connected with the final version of the game and had no influence on it (it was a leftover file used during the development to estimate memory usage. It had no effect on how much memory was actually allocated). Perceived performance increase after editing the file may have been related to restarting the game.

 
Console-specific

• Improved image sharpness with Chromatic Aberration and Film Grain on.
• Settings should no longer reset to default after several game session restarts.
• Fixed visual issues occurring during the transition between The Heist and Love Like Fire.
• Corrected the look of several vehicles.

• Telemetry consent request will appear once more due to an earlier issue with settings reset.
• Fixed an issue whereby it was possible to fall down the elevator shaft in Megabuilding H8 in Automatic Love.

There are still a lot more bugs yet to be fixed.
