Proton Versions Tested

• Proton Hotfix
• Proton Experimental
• GE-Proton 11-1

Expected Behavior

Before the latest Overwatch season update, the game worked correctly:

• ~240 FPS
• Character models loaded correctly
• Weapon models loaded correctly
• No crashes

Current Behavior

After the latest Overwatch season update:

DX11:

• Poor performance compared to previous season
• Practice Range and matches eventually crash
• CPU usage becomes very high while GPU utilization stays relatively low

DX12 Beta:

• Performance is excellent (~240 FPS)
• Hero models are invisible
• Weapon models are invisible
• UI and maps render correctly

GE-Proton 11-1 crashes even faster than Proton Hotfix/Experimental.

Troubleshooting Performed

• Tested Proton Hotfix
• Tested Proton Experimental
• Tested Proton 11
• Verified Vulkan is using NVIDIA GPU
• Verified OpenGL renderer is NVIDIA
• Tested X11
• Updated to NVIDIA 595.71.05
• Created fresh Proton prefix
• Removed custom launch options
• Generated Proton log

Other Proton games such as Deadlock and Star Wars Battlefront II run normally on the same system.

Regression

This worked correctly until the latest Overwatch season update.
