Hello, I already mentioned my performance issue in the release thread but thought I'd move it here:
For me, the N11.1.0 geoscape is running way slower than N11.0.2, Harmony on OXCE 8.1.0, or any other OpenXcom mod I have ever played (unfortunately I couldn't find OXCE 8.1.1 to test). I don't know what the FPS is but it feels like I have gone from the usual capped 100 to somewhere around 30. I have checked both version several time one after the other to make sure I'm not imagining things and the difference is night and day.
I'm using 100 hz 1440p display, I have Ryzen 7 78003dx CPU and RTX 4070 Ti Super GPU, and I'm running Windows 11. It's a desktop and the game is definitely running on my main GPU. The OpenXcom/OXCE framerate limits and/or OpenGL vsync settings have no influence on my issue.
I initially updated from N11.0.2 to N11.1.0, then I did a fresh install of N11.1.0 and the same performance reduction is evident as soon as I start placing the initial base (which, I assume, means the issue happens even before any geoscape scripts start running). I have tried changing the geoscape scale (1x is laggy in both versions but 3x is only laggy in N11.1.0), I have tried OpenGL, Non-OpenGL, and disabled shaders. I have fiddled around with the CPU affinities to make sure that's not the issue.
The only obvious difference (other than the FPS drop itself) that I can notice between the two versions, is that N11.0.2 is using 10-17% of my GPU while N11.1.0 in the same situation is using only 5-7%. I suspect that is what's bottlenecking the N11.1.0 performance but I have no idea what is causing it.
edit. GPU driver update and trying various settings in the NVIDIA control panel has no effect either.
