I recently upgraded to Rx 5600xt msi mech from rx 570 4 GB, at first all games ran great but suddenly fps significantly dropped in all games (The Isle, War Thunder) i used to get around 80-90 fps on maximum setting in War Thunder and now barely getting 30 fps same goes for Isle use to get 70 fps on high setting now can't even get stable 30 fps, Tried reinstalling Gpu drivers after deleting old one with DDU, I tweaked fan curves because temps were a bit on the higher end because of bad airflow, any tips on how can I fix this issue? PC specs are (I3-12100, RX 5600 XT msi Mech, 16Gb ram 3200 MHz)
 
Power supply?

Furmark stresses the GPU quite a bit, but doesn't really require much else of the system to be working. I would expect more then 50C under a full load. A tool like Hardware Monitor could reveal the reason under PerfCap.

Double check that your CPU temperatures, motherboard temperatures, etc are all also in check.

Check if there are any motherboard BIOS updates available.

have a cheap Chinese power supply. it ran just fine for a few days temps were a bit high so I tweaked it with fan curves and they were normal after that

I'd be surprised if your PSU was the problem because if a card draws more than a PSU can provide, it results in a power-off system reset.

I say this from experience. When I bought my first RX 5700 XT, it was an XFX Triple-Dissipation model. I was getting power-off resets during gaming and had no idea why because I knew that driver crashes don't cause the PC to reset. When I put my old Sapphire R9 Fury Nitro+ back in, all instability disappeared (I was still using the same driver installation). I sent the card back to XFX and they replaced it with a THICC-III model. I immediately noticed when I was installing it that the auxilliary PCIe power connectors were different. Where the Triple-Dissipation card had an 8+6-pin connector design, the THICC-III had 8+8. It dawned on me that my first 5700 XT was probably trying to pull more power than the 8+6-pin configuration could provide but not more than 8+8 could. My PSU was the same EVGA 1000 G2 Supernova 1kW PSU that I currently use today with my RX 7900 XTX so I knew that there was plenty of power on tap.

I honestly think that your card is probably worn-out. I remember that RDNA1 was very effective at mining Ethereum. Mining doesn't really wear GPUs out as long as they were properly taken care of. Unfortunately, a lot of the time, this was not the case. So, you might have purchased an ex-mining card that wasn't taken properly taken care of. I hope that it's not the case but your results tell me that the card is probably dying.

I did bought it Used but i can get it replaced, don't understand why it did work fine the first day lol

Power supplies can cause weird issues. First thing might be replace the power supply with a quality unit. May not change things, but at least you’d have peace of mind of not blowing up your pc. Then you can move onto the gpu.

5600xt is still a decent card but it would be good to know its temps etc. But if your power supply is cheap, maybe it’s holding back the gpu a bit? In either event power supply imo is your place to start as if you get a newer faster gpu in the, you don’t want to damage the new card.

But with rdna1, definitely want to be sure to have some airflow around the card. If you are going to replace the card anyway might be worth to take the cooler off and replace the thermal paste just to see if it starts acting better. You may get lucky and it might work for years.

reinstalled the gpu drivers with ddu. and ran furmark and was getting around 200 fps, as soon as I ran msi afterburner fps dropped to 40, tried turning it off but still getting 40 fps
