A week ago, I installed an XFX 6750 XT Core graphics card in my computer. The card performs quite well in terms of FPS, but I’ve noticed a few concerning things.
Under load, the card creates a loud "buzzing" sound, and undervolting or setting an FPS cap deosn't help. When the card is idle, it makes strange noises similar to those under load, but quieter and they sounf like clicking (it’s not the fans, they turn off when I'm not gaming).
I've also noticed that sharp texture edges in games appear slightly pixelated. Enabling FSR in The Witcher 3 eliminates this issue, but in Cyberpunk and Space Marine 2 it makes it worse ( in Space Marine 2 it's almost unnoticeable, in Cyberpunk it’s a bit more visible).
In Cyberpunk, I occasionally see other graphical glitches. Some light reflecting objects in the distance have black pixels on them, which disappear when I get closer. When I exit the map, all textures temporarily become much brighter, as if all in-game lights had intensified for a few seconds. I've also encountered strange graphical bugs that only occur in a specific location at a certain ingame time (I’m attaching a video of this). I'm not sure if this is an issue with the GPU or the game itself.
Are these issues something to worry about? I've had pretty bad luck with electronics recently, so I just want to make sure everything’s fine. I built the PC six months ago, but I only installed the GPU now.
