Hello guys.
I am writing here as I can't find solution by myself. Also did not find solution over internet.
I am playing KSP over Steam - no mods. I updated game to 1.11.1 last week and it's extreamly slow. I can't build even a simple ship. Game is loading for 20min. Menu has like 5FPS, in game is same, even in builder. Totally unplayable. Game did not crash, it's just slow.
I updated all Invidia drivers, PC is updated, I did make sure that game runs with nvidia etc. I tried installing it on SSD and it's same.
PC is laptop HP Pavillion, i5-6300HQ CPU 2.30GHz, Geforce GTX 950M, 8GB RAM, fresh win10 64 install, bought not cracked.
When game is running slow it's at about 2500MB CPU and 95% GPU.
I found out that if I downgrade game to version 1.5 it works smooth as it was working before (CPU same 2500MB and GPU at 20%). Tried downgrading to 1.10 and it is also slow. Did not try other betas. I tried all settings on lowest possible setting, V-Sync on/off, and it's same. It's something that overloads GPU.
Please help, I just want to play.
Thank you all for your help and answers.
