Performance Issue with Intel Arc B580 in VRChat - Low GPU Utilization & Inconsistent CPU Scaling

[akisuran]

I tested the B580 in VRChat at 2K resolution using two different CPUs: the Ryzen 7 5700X and the Ryzen 7 5700X3D. The performance gap between the two CPUs was substantial.

When using the 5700X, the GPU utilization consistently hovered around 60%, and the average frame rate was significantly lower compared to the 5700X3D. Specifically, the 5700X resulted in an average frame rate that was 56 frames lower than the 5700X3D. This suggests a bottleneck caused by the 5700X

In some specific scenes or maps, the frame rate difference can be as high as 50%

Driver Version: 32.0.101.6559

Hi, akisuran.

Thank you for posting in our Community and for sharing the detailed information about your performance issues with the Intel Arc B580 in VRChat. I can see that you’ve done a thorough comparison between the Ryzen 7 5700X and the Ryzen 7 5700X3D, and it’s clear that the 5700X is causing a significant bottleneck, as shown by the lower GPU utilization and frame rates. I’d like to gather more details and verify specific information such as the OS builds, exact driver versions, and any system errors. Using the Intel SSU tool will allow us to collect comprehensive data about your system setup, which could help in pinpointing the root cause of this issue.

Have a nice day!

Hello, akisuran.

Thank you for quickly providing the SSU data. I’ve received the system details, including the OS builds, driver versions, and error information from the Intel SSU tool. However, I’m curious, are you using a VR device while playing this game?
