This one is strange. Trying the new relentless frontier demo, i have some really bad sttuters/freezes with vulkan. With opengl I dont get those sttuters, but the framerate is lower. I decided to check other gzdoom games (Selaco, Hedon, vainilla doom). All of those have sttuters, although vainilla doom had way less than any of those other games i tested.
I tried gzdoom versions 4.10.0 and 4.11.0. Maybe is a driver issue? I didnt have sttuters with Hedon back then

Re: Sttutering
I can't speak to stuttering during gameplay, I don't think I tried 23.9.2 for long enough to experience such a thing, but 23.9.3 has some severe issues with locking up the display driver for over ten seconds on alt-tabbing from GZDoom so there is definitely some weirdness going on with AMD drivers as of late. I rolled back to 23.9.1 for the time being and don't experience any other untoward symptoms - I'd recommend you do the same and report back.

Re: Sttutering
Well, that did the trick. Downgrading to 23.9.1 stopped the constant sttuter. I think the fps are a little lower though (From 75 to 72, probably).

Re: Sttutering
Oh, AMD screwed up their drivers again? Hardly surprising news...

Re: Sttutering
I really wish they'd adopt a more comprehensive QA process. They're far more ethical with their AI technology than NVidia could ever hope to be with their current board, and I really would hate for them to keep screwing things up repeatedly with Vulkan like they did with OpenGL for 2 solid decades. Shit like this just keeps solidifying NVidia's dominance, and it's painful to watch, especially when they could lead by example with open source technology.

Re: Sttutering
Anone wondering why our survey yet again reports AMD as the clear loser in user share among the 3 manufacturers?

Re: Sttutering
That's what disappoints me the most. Of the 3 they are the slightly more ethical of the corporations (even if they are still ultimately a corporation) and do less of the money-grubbing fuckery than the other 2 do, and that includes their open source projects such as FSR1/2/3 and drivers for Linux. Get a QA team, and a more serious commitment to their LTS drivers (aka "CAD" drivers, the ones that update less frequently) - especially with stability and less frequent introduction of bugs, and master the RTX technology - and they probably could potentially choke NVidia right out until NVidia starts upping their game.

Re: Sttutering
Bump. For anyone who might still be paying attention to this thread, I have upgraded to driver version 23.10.2 and am not experiencing any previously mentioned issues.
