PP 22.4 crashing high-end system, causing restarts, stuttering and scratchy audio

[alexd97401411]

Hi,

I'm using PP 22.4 with a brand new, seriously high-end PC editing suite. I'm having some strange issues that I haven't experienced on other builds.

I'm experiencing audio stuttering and scratching in the timeline (audio of the clip is fine) even on the lowest playback resolution. Audio latency is set to 100.

I'm also getting major crashes when I ask PP to perform intensive tasks - e.g. opening up all the scopes in Lumetri, opening a large project. This crash simply reboots my computer. There is absolutely no chance of overheating - I have 6 fans, water cooling and my GPU and CPU temps are sitting at around 45 - 49 degrees C.

I've experimented with both NVidia's latest studio and game ready drivers. The studio drivers make PP 22.4 perform even worse. 

Here are my system specs. Full DXDiag attached.

Many Thanks.

Edit: After a lot of trial and error, I found that this was caused by daisy-chaining two monitors with display port cables. The issue was resolved by plugging both monitors directly into the GPU.
