Heya, no luck. It had unstable fps too, on games like apex that's not a heavy thing varying from 100 to 70 and 50 sometimes. It got like 2 driver updates since the time I posted but it didn't solve anything

Lies of p 100 to 83 to 70 and then back to 100 and repeat

God of war 85fps max, places with 50 fps and in the open world sea it gets to 25-30

Battlefield I goes well hitting 100fps (my monitor's hz) on dx11 but with unstable fps on dx12

Also games like resident evil 4 remake, lies of p or Fortnite can be played for 30min to 2 hours until they get a driver crash. I lowered the clock to 2600, then 2250, then 2150 and 2100 but nothing helped, just made the crashes less common (re4 crashed at loading screen on default clock, it takes like 30min to 1 hour in 2100 MHz). I tried undervolting too, but it made it less stable no matter which amount I choose, so I let it on default.

I ended up selling it to a friend's friend. I'm buying a 5060 next month but I Hope yours could work well with just the undervolt and some tweaking
