Unplayable with Directx12 on Intel Arc B580

https://www.youtube.com/watch?v=YVtKOw8PtMc

the game on this GPU seems to work the same no matter the detail settings I use.
I get around 100fps with static scene, when I get into combat in maps the fps drops to around 30 and stuttering occurs -- even in lowest settings.

I'm not sure if it's the drivers for the GPU or it's on the game's side.

Vulkan is okay, but when you're playing with windowed fullscreen instead of fullscreen some minor stuttering still occurs. Also Vulkan may stutter if you don't lock your fps.

Do you enable Rebar on you machine?

It may give huge performance boost on first cards afaik.

You still can mod bios if you system does not support it.

(you may try linux setup for it - just enabled with no bios mod by a system default)

Yes. I have ReBar enabled. Game works okayish on Vulcan, but Dx12 is unplayable. It might be on the drivers side, but I posted this to GGG just in case.

In this video there are issues presented I talk about. The game can drop from 90fps to 20 fps and heavy stuttering occurs with DirectX12. It's a shame because GGG added support for XeSS and we can't use it.

Oh, i see.

Afaik you may use some modded software to enable FSR** on any game which non intended but don't know if it would be work for this card.
*just to reduce loads and watts/hour but this may be unpleasant to use koz of bad quality (as i heard for amd upscale). you may try and compare it with just NIS**
**if i remembered tech names correctly

*also can you see real power consumption of system/graphics. i just have 300 watt PSU and worry it would be not enough

Bumping this.

The issue persists and is made even worse with the newest Intel driver.

Can confirm it's still happening, Intel Arc B580 with DX12. Works decent with Vulcan and FSR, but would be nice to utilize XeSS as GGG added it. Intel driver 32.0.101.6647

Can you use Vulcan tho ? my game keeps perma crashing with it and dx12 performance is horrible cant even get 20 fps.

Same here

A B570 here, Vulcan started out super nice the first 1,5 maps with some friends, clear and about 70-80 FPS when sharkenado ++ was flying all over the screen, but after i loaded a map for myself i had a game freeze, after then the game is not launchable in Vulkan, just perma freezes it. I so want Vulcan to work here since performance is like 500 times better then Dx12. What irritates me is that i got a taste what Vulcan could do.
And I have tried removing all drivers, reinstall drivers, win 11 repairs of reg, installed PoE client from their web page ++, aftrer reinstall of drivers Vulcan worked again for about 20 min before games goes into perma freeze so there is some driver issues here.
Will try to downgrade some drivers tomorrow to see if that can help.
