Can't run new patch in WINE

^

So, i played for a while and have noticed no serious problems.

With my low-end Radeon card, FPS was terrible to begin with, but it didn't seem worse than usual.

I have found quite a disturbing problem. When I hit something, I experience FPS drops. The FPS is fine if a lot of stuff happens on the screen or I attack, but whenever I hit something, it goes down (so it does not seem to be a problem related to graphics). The more monsters I hit, the worse is the FPS drop (very visible with Spectral Throw, if I aim at empty space, all is fine, if I aim at a group of monsters, frame time can increase to 500 ms easily).

It makes me feel like if there was some really badly implemented function somewhere in the depths of Wine, but I am not able to determine what exactly it is. Attacks seem to be less affected than spells, it wasn't very bad if I dealt many hits with Blade Vortex, but Spectral Throw was particularly bad. I tried wine 1.9.3, 1.9.3-staging, 1.9.4 and 1.9.5, but there seems to be no difference.

It doesn't seem to throw anything into Terminal except:
fixme:d3d:wined3d_debug_callback 0x35679d0: "Program undefined behaviour warning: Sampler object 12 has depth compare enabled. It is being used with depth texture 65, by a program that samples it with a regular sampler. This is undefined beahviour.".
But that message appears there all the time, even if I don't hit and experience no FPS drops, so it's probably unrelated. Any idea what can it be? I have never experienced this problem before.

It runs with 60fps as long as nothing is happening. When i start casting -> 20fps, when my freezing pulses hit mobs, even less. Fights in a party are borderline impossible. That on wine 1.9.4 with a gtx860 on an i7... bleh

It used to run so fine on the 1.7.27 from PoL that was custom-patched for PoE. It didn't even lag when windows users in the party were already complaining.

Seems the fps drops when hitting stuff with attacks/spells isn't entirely linux- or wine-specific though. Windows users have similar problems, lagging out in big packs...
