Haven’t checked notifications, glad I’m not alone here. The Vega having similar or same issues makes it more interesting.
My bet is on AMD’s drivers. If you peruse the forums there are numerous people mentioning the same issues with their cards in multiple games. Here’s what’s been really interesting for me lately…
Call me crazy, but it’s almost like the card/drivers have to adjust for the game you’re playing. The production version of Overwatch was having all the issues I described, until sometime yesterday, it mostly went away. I have no clue why, nothing changed on my end. Then I join PTR, and guess what, more stuttering and massive framedrops, exactly like I described in the OP. I’ve since been playing PTR for about an hour today and it appears gets progressively better overtime, still with some FPS drops.
I have no explanation for this. You’d think the results would be consistent for every play through, but it seems the more I play the game, the better my performance gets. It’s still not stable. I could put my 980 in right now and the issues would go away, but I’d rather not do that
Also Neocry thanks for saving me the trouble of buying a third party cooler for the time being, lol. I’m holding off on that for now. But to tell the truth my card never goes above 80-82 at max, with WattMan’s auto-undervolt enabled. Even before then it never got hotter than those temperatures.
However to end this long rant, I have received two crashes in the middle of a game, both in production and PTR within the past two days. Not a rendering device error, just a generic crash. So that’s disconcerting.
Edit: Sorry I need to add to this, because I didn’t realize people above were basically saying the same thing about the FPS ramping up. In my case I went straight from production to PTR within the same sitting last night. The production version was sorta fine after a while, but immediately after joining PTR I got the issue again, even though the card was already “warmed up.”
