Expected Behavior

I expected OBS to perform as it has done previously. CPU usage was anywhere from 4-6% when running. It now sits at almost 3% idle.

Current Behavior

High CPU usage at idle, running at 12-15% when under load. previously OBS would idle at <1% and under load would be around 4%. I have made no changes to any OBS settings. I believe this is related to the new windows update which OBS is having conflicts with.

Several times during the stream, the Twitch chat and activity feed would go blank for several seconds and reload, sort of like they were crashing for a few seconds. At one point, it caused OBS to crash. I am unable to decipher the crash log so I am not sure what happened specifically.

Steps to Reproduce

1. Run a stream
2. Observe high CPU usage and chat/activity feed blanking out for several seconds.

Anything else we should know?

This was not an issue until this week. Over the weekend my PC forced updated Windows to 24H2. I believe this is directly a result of the update, and OBS is having compatibility issues that require addressing.
