dx12 issues

pwesty · October 31, 2022

I'll start off with my current specs that matter for this question and issue...

5950x
64gb ram "3600"

1tb 980 pro nvme

aio cooled
asus strix 3090ti LC
1k EVGA 80+ gold PSU

Issue is this:
about a month ago, i updated my GPU driver on my "OLD 6900xt" GPU. when opening Edge browser, i noticed video glitches so bad it would flash off my screens for a second and come back on until i closed the browser out. i reinstalled and still to no glory had this issue. here is the issue i had with the 6900xt. via youtube.

If you look at the right screen you'll see edge flicker a little bit and then both my screens go dead for a second then come back..

well i seriously thought this was my gpu after self diagnosing and reinstalling everything. i returned this gpu and got the new current GPU.

A few weeks go by, zero issues at all nothing at all. not even a flicker. then it started happening again on the new WoW dragonflight pre-patch.

I noticed directx 12 was enabled by default. "after about 1hr of pondering why i took the 6900xt back and feeling guilty" i was like well that makes no sense it cant be that.
well, i changed from directx 12 to directx 11. IT FIXED IT!! no more issues in game, but still have issues with windows itself because of dx12.

If i screen record, these issues can't be seen. if i go live via twitch and these issues happen, it cant been seen but only by me.
i changed out DP cables to better ones, i made sure my PSU wasn't over or under volting. i checked my temps on everything. everything is acting perfect as long as the application is dx11 not dx12.

Motherboard, PSU or CPU is all i can think of as the possibility of a truly broken gpu not rendering dx12 isn't possible twice in a row. but im not 100% sure.

i even "upgraded" from win 10 to 11 and didnt fix the issue. maybe a full reinstall will fix it, even though ive truly tried that with the old GPU.

i need some more expert advice why dx12 games and apps are messing with my GPU like this.
