Something is terribly wrong with Shaders since 3.27

BUMP

same here

This whole bad performance as i see is not only beacouse of my potato pc. Most strange for me is why it touch some players (btw. a lot players) but in same way a lot players only complain on loot density and etc.?

I also have old hardware so I was never lag free even in previous league. I dont expect it to hold forever but I believe that there really is a problem. Shader is maxed all the time, fps is about 10 and during going to other zone, it freezes and dissconnects.

I tried to troubleshoot it, tweeked settings, updated drivers, nvidia settings, windows settings etc.

I also believe the main problem is shader loading. I cleared poe shader cache. Then I realized my drive is filling up very fast (30 GB of free space just went somewhere). I went through it with wiztree and realized that nvidia shader cache is about 27 GB. I cleared it.

It didnt help. I tried to go through one zone in campaing for about an hour. Took 5 min to load the town, then another few to teleport to the zone. Then I stuttered through the zone in 10 fps and game disconnected or outright crashed when I tried to move to the next zone.

After hour of this I checked nvidia cache again... It was 5,6 GB.

So... Even when I was basicaly in the same area for 1 hour, shader bar was full entire time and it generated 5,6 GB of fluff. Thats why it falls apart so much. It is trying to download mountain of data. Something has to go in circle there after 3.27 patch for particular drives/setting combination. There is no reason to download 5,6 GB of data for a single area that got generated during first visit.

here is an example, when cringe things happen:

10 FPS


and when everything is normal

Yep! Exactly the same!

bump. same problem.

My game has increased performance when i try using poe_x64.exe directly from poe folder instead using client.exe.

i dont know if my issue is shader related BUT i was having wicked long load times in ANY town during the campaign, i also play on a potato pc (no other options)

things improved a bit for me after i switched from dx12 render (the one that was best for my setup)

i switched from DX12 to DX11, played a bit and found it was MORE laggy and had lot of stutter, (i assume it was building shader cache)

but then when i siwtched back to DX12 again, (somehow, i really dont know why suddenly things improved)

i went from playing without seeing enemies, lag in towns, to actually seeing what the new breach enemies look like

i came to post this even when the info i provide is dubious and little because i honestly dont know what happened but things improved a bit for me, hope it helps someone

and hope this performance thing gets adressed because eventhough i play on poorman's hardware i am sure it is not an issue on my side

Each renderer has its own shader cache, the reason your performance dropped when you swaped is because it had to start all over from 0.
When you went back to dx12 those shaders were already compiled.

The problem is not with any particular renderer, its probably something going on with the compiler missing optimizations or using some kind of shader model preset that is WAY too demanding for a game like PoE which doesnt really need it, could even be a priority issue on the threads with the game trying to meet an fps quota and only using idle resources for shader compilation / execution.

It might be time to give users a tool to compile every single shader the game has outside the game.
