6.9.x VM Gaming - High fps, but stutter every 1.5 seconds affecting in-game units/characters but nothing else.

[Kudagra]

I'm having a really odd issue with any version of 6.9.x... When gaming in either my Mac or Windows VMs, I have high FPS but the game's units/characters stutter every 1.5 sec or so. The weird part is that the camera, screen movement, and mouse are all flawless. It's only the characters that stutter. I've attached videos below for examples.

 

I'm using passed through hardware- 3950x and 6800xt (I've also tried a gtx 1080 with the same exact results)(This happens with both a 6800xt and a GTX 1080, but the issue goes away if I go back down to 6.8.3.)

Some sort of CPU scheduling perhaps?  Have you got the CPU cores pinned?

This sounds helpful?

I've done all performance improving steps I could find (from that thread and many elsewhere), but I'm pretty sure I've narrowed it down to being a network issue. I had this problem when I first upgraded on release, and quickly reverted. I didn't realize until recently that it's the same problem so I'll revive my previous thread I started at that time.

 

I appreciate your help regardless, though!
