Hi guys. Long time lurker. So ive been flying 20-30 part ships for about 2 years now due to my low fps. Cant really get past duna on account of that. I have scoured these forums and have done every combination of graphic settings and tweaks, but regardless of what I do my frame rate is usually stuck around 12 fps max is about 25. Every thing I have read points to a cpu issue, due to the game engine, but I figured I might as well ask before I stop playing all together. Maybe you guys see something I have missed. Heres my specs, amd fx 4350 4.2 cpu, msi 970 gfx, 12gb ram, ksp runs on my ssd. Here are things I have tried. EVERY possible combination of graphic settings with no results, changing settings in nvida control panel for ksp with no results, running the game in opengl with maybe 10 fps improvement (maxes at 25 on small craft),and messed around with the cpu affinity for ksp with no results which I have read is pointless. The only thing that had a positive impact was changing the max physics delta slider to .03 which did give me a boost to about 33 fps in some instances, but usually dropped back down on landing maneuvers or take off. This is a definitely a cpu issue, correct? Any thoughts on ways I can improve this? Any input appreciated!
