So, I was playing ksp and realized that the game was laggier than before, so I decided to try to find out why, after a few minutes I noticed that ksp was using my intel video card, so I changed the card to my NVIDIA GeForce GT 1030 and I launched ksp, Instantly I noticed something weird, the screen on the main menu was kinda wobbly, but I though it was nothing important, then I make a new world and noticed that the screen updated slowly, like some sort of rolling shutter, (I had mods installed at that moment, so I took them off) And the effect was still on the stock ksp, 0 mods. I re installed ksp and the thing was still there, so I start to mess with the ksp settings, enabled vsync, disabled it, reduced fps limit, increased it, set the ksp to fullscreen and windowed screen, Updated my card drives, restarted the computer, search youtube and internet for an answer, and I decided that after 2 hours trying to fix this, I would just change back to my intel crappy video card, And guess what, the screen tearing dissapeared, So now i have to select 1: Unplayable modded and annoying stock ksp thanks to screen tearing or 2: Unplayable modded ksp thanks to lag, but without the screen tearing, after 1 more hour of messing around, I decided I would make a forum post to see if anyone could help.
Heres what I mean with "some sort of rolling shutter effect on screen"
This is how it looks with stock, Its not unplayable, but noticeable
This is how it looks with mods, Its unplayable, and impossible to make a film with.
