PC Graphics

Hey guys,

two of my friends have bought a Red Devil 7900 XTX. Both are very happy with the performance of the card, but also have various problems. Especially in Unreal Engine 4 games.

In Satisfactory and Grounded the power consumption is very high and the temperatures as well and in "it takes two" the card consumes constantly 375W and boils at 105° edge temperature with miserable performance. Any idea what can be done to prevent the cards from destroying themselves? My 6900XT runs absolutely smoothly and is even significantly faster than the 7900 XTX in "it takes two".

Hi @wuchzael,

Could you answer some questions, please?

1. Are both your friends with that card experiencing the same problems?
2. Do the GPU fans run properly?
3. Have they adjusted the GPU fans to run slower, because of noise?
4. Have they done any GPU overclocking with MSI Afterburner or similar, especially raised the voltage?
5. Are their PC cases ventilated properly and not underpressured?  If so, heat can accumulate inside the case and be reused by the GPU fans.  See video below.
6. What's so special about It Takes Two, is it known to be resource demanding?  I've not played it but it looks to me the graphics are not very demanding, at least.
7. Are they using the latest GPU drivers from AMD?

Maybe it's the Warming Up the Snow Globe sequence in the game that's heating the card too?

Thanks for your help. I'm a semi-professional PC-Builder (worked in a pc shop for some years and studied computer science) but I've just no clue why the 7900 XTX is behaving like I described. It's only in unreal engine 4 games, other games run perfectly fine on both mentioned cards.

But to answer your questions:
1. yes
2. yes
3. no
4. no
5. yes
6. I don't know! It must be an issue with RDNA3 architecture and the game engine. 
7. yes

As soon as you start this game the cards go nuts.

You could ask AMD for official support, or rather your friends who own the cards could.  In the mean time, I think they should avoid playing the problematic games to avoid damaging their GPU cards.  Since they get bad performance in those games I guess they're not enjoying playing them anyway  The bad performance is probably due to thermal throttling when the cards overheat.  Not good.
