In my case, moving the windows "Saved Games" folder to the new drive solved some sttuters and also gave a little perfomance boost.
I dont know the reason, but it worked. Maybe the "fxo" and "metashaders2" folders.
I played Microprose's F-19 Stealth Fighter with 640KB RAM and a Intel 8086 Proccessor at 8 MHz (10 MHz with Turbo Mode). There was also a Su-25 Frogfoot Simulator, I cant remember its name... They ran at 8 FPS in low settings, maybe :smilewink:
