Hey, first off fantastic plane, I don’t think I’ve enjoyed a sim this much before! The depth and the challenge to fly this is great!
I noticed while flying out of CYRV at night with rain up into FL300, the sim would have a slight flash from the rain, a frame pause and then continue on, occurring roughly every 3 seconds. Disabling rain and ice effects gets rid of this completely. No issues when on the ground or taxiing, low level it was fine, only after climbing up several thousand feet did it start to occur. For reference:
3840x2160 4k main monitor
2560x1080 secondary (SimBrief, FSGRW etc)
Addons used in conjunction:
checked the performance of the system, no thermal throttling, CPU individual core useage not maxed, ~70-80%, GPU 50-60% useage. I can attach log if need be. Superb performance otherwise!
