Thanks, but I think dcs.exe should be the file to rename also for non-steam versions? That's what is running when we are running the game? The updater launches into DCS.exe, doesn't it?
Anyway, I tried renaming the updater filename to Boneworks, and followed all the steps in the first post here. Didn't see any improvement at all.
Also, according to nVidia, the game must use forward rendering, and I've read that DCS doesn't use that.
