October 23, 20214 yr Hi all, anyone have experience of poor FPS at night and solutions? I have tried everything from removing all shadows, LOD reduction, clean .cfg file in case it was a tweak issue (I had modified light points to 900 but that doesn't seem to be the issue), but I still get highly erratic 20-30 at night in cities/large airports versus smooth 40-60 in daytime. I have i7-9700K OC 5GHz, 4K monitor RTX 3080Ti, 32gb RAM, everything on NVMe drive. Running FSLABS, ORBX pretty much everything. Any clues appreciated!
October 23, 20214 yr Long time ago i did brilliant move - deactivated fps counter, Coming to ur question, for me it looks like u have unlimited fps, i have locked mine at 30 ( NVIDIA Control Panel ) and it is rock solid ( day or night ) on computer that is weaker than yours. Artur

Yeah I hear you, I don’t normally have the counter on but it’s badly stuttery. I don’t think locking it at 30 will help if it’s 18-25. I’m sure it’s a setting or tweak I have missed.
October 23, 20214 yr I have no any tweaks apart of cores management via Process Lasso. If u have stutters then it is pure indication that ur GPU is overloaded. Reduce ur settings and try to find sweet spot for ur system. Unlimited fps is a source of instability and fps fluctuation. Edited October 23, 20214 yr by Beardyman Artur
October 23, 20214 yr Are you using dynamic lighting *and* SSAA? That tends to kill performance. I run 8x MSAA with DL at night.

November 2, 20214 yr Author If anyone is interested I seem to have fixed this by following advice from a PMDG forum related to night lighting which involves deleting shaders folder, plus deleting shadersHLSL folder, then re-installing (or repairing as I didn’t actually uninstall it) 5.2 Client.
