FPS drops after minimizing the game during rainy weather
When it rains, my OpenMW sometimes suffers from a HUGE slowdown, the latest one was from normal 100+ fps to like 10-15. Here are some observations (+screenshots with profiler overlay on): 1)screenshot 1,2: the slowdown itself. If I save and reload game now (without closing OpenMw), performance does not change. 2)screenshot 3,4: FPS goes back to normal when the rain ends. 3)screenshot 5,6: if now I load game saved at p.1 (when it's still raining), the performance will still be normal. 4)Performance tends to degrade over time: it has restored to ~100fps at screenshot 6, then I left Openmw running for 20 minutes, and it is already hitting 30.
OpenMW-0.43.0-RC1-win64, no mods except simple texture replacers, view and cell load distance options are all default. My config is i5-3570 4*3.8Ghz, 16GB RAM, GTX 1080.
