Hyee , just like everyone else im really looking forwar to the 1.1 update. but i think that until it hapens i could help some people having isues.
I am the owner of a system based on AMD parts
system specs :
amd fx 6300 hexa core not overclocked (yet)
Msi R9 380 Gaming 4GB version
16 gb ram etc and a windows 10 OS
ive been in the same situation as you sir. KSP ran better on my crappy laptop than on my pc so a few months a go i did a lot of research and tried a lot to fix it and now im running a 64 bit ksp modded to heaven with the best visual mods and it runs better than ever since 1.0.5
now how did i achieve it ?
ofcourse the 64 bit community workaround
but also the radeon control centre is very important, sometimes the standard windows 10 updater doesnt update ur GPU driver like its supposed to so the best is to do it via the radeon control centre but over there you have to manually do it it ll give u pop up once there is a new driver available but it doesnt mean it ll install it automatically since i started installing these driver updates via the radeon centre the performances of my pc have only got better in multiple games not only KSP
64 bit ksp is the way to go at the moment it takes some time to figure out and such but the nice guys on the community workaround forum thread ll surely help you.
btw. English is my 3d languageand im to lazy to control my spelling.
hope this helps for some people
