Just wanted to chime in and say the same is happening to me.
Vega 64 gigabyte oc
Playing at 1080p high
Hi from Russia
Vega 56 latest driver (Red Dragon Vega 56)
Got same problem weapon sight pixels.
Interesting that inside houses no problem at all but if you look some where like on groun then on tree or whater it happens again and again they didn fix problem even in 20.4.1 driver that came just 4 days ago.
Next time will take nvidia sorry amd. and other problems with old games as Ghotic 1/2 for exemple stuttering and lagging.
Hey, I heared from a mate. He have Nvidia, same issue. Money is not a problem for me, but change to Nvida 2080TI won't fix the issue, and I still feel Nvidia is rip you off.
I just registered to tell you I have the same issue (Vega 64) Please for the love of god keep me from buying Nvidia and fix this!
on battle.net go options->game settings, tick additional cmd line arguments and type -d3d11
cod hasnt crashed since i done this
IW released patch 1.19 and the problem is not fixed.
I still have this issue on my Vega 56 and my friend on RTX 2070...
In Black Ops 4 everything is okey... well maybe in BO5 we will not gonna have this problem.... :/
