so with 0.3 steamdeck support is officially dead I suppose

I was able to finish the campaign and somehow survived most of the time 3 fps and graphical glitches (HUD starts flickering uncontrollably) during any abyss encounter, but after reaching maps it was harder and harder to enjoy on this device. I switched to gaming laptop with rtx 3050, continually lovering both resolution and details to the point main character is unrecognizable and yet in tier 12 reached again point where 3fps around abyss are norm, but this time starting to killing me. Too bad, 0.2 I quit before finishing ACT2, 0.3 I have been enjoying very much even in end game, but since tier 12, for 10fps game the monsters move just too fast and its not fun to lose one map after another :D

I have been playing on steam deck. Didn't reach maps on 0.3.0 yet. I did reach on 0.2.0. For the most part was playable. When there are a lot of enemies it gets slow. SPECIALLY when it has to load the enemies. So for example, I make sure to fly away whenever triggering strong boxes, because If I stay to witness the loading, my steam deck will freeze for around a minute. But otherwise I was able to play basically.

My current settings:
- Vulkan
- Vsync off
- 1280x800
- Bilinear scale
- Max render resolution : No upscale
- 15% sharpness
- No HDR
- Medium Textures
- Trilinear filtering
- Lighting: Shadows
- Low Shadow quality
- Low Sun Shadow
- Low number of lights
- 25% Bloom
- Low Water Detail
- No Mvidia Reflox
- Foreground/Background FPS Cap ON, 30
- Triple Buffering ON
- Dynamic Culling ON
- Target Framerate 30
- Multithreading Enabled

Yes, campaign is doable, with occasional slow downs around abysses, and I also found the solution to always lurk on the edge of concentrated mob group, keep them outside the screen and constantly run away (with ranged build only I suppose), but eventually you just start thinking if you are not trying too hard to make something work, that is not ment to work, given the number of monsters and efects.

Might want to try to disabling tripple buffering and then if it wont do much maybe try dx instead of vulkan. Im on old pc with gtx 1650 i think, not in steamdeck but i managed to find satisfying performance by playing with settings
