Sorry about the necro posting, but I thought I'd post this incase it helps others. Ijust installed Tiberian Sun and experienced this issue, which I fixed it by adding "maxgameticks=240" (might be higher/lower for other machines) in the "ddraw.ini".
Note, ddraw.ini is a file from the community patch; this won't work unless you install that patch first.
Apologies, I didn't explain properly.
I copied over the "ddraw.dll" & "ddraw.ini" from "The Dawn of the Tiberium Age stand-alone mod". What I should've said was that I didn't replace the Tiberian Sun Origin .EXE, but copied over those ddraw files. This also fixed the "invisible menus" issue.
The Tiberian Sun patch I'm sure works just as good or even better, but this works for me without replacing any files.
Well, the TS patch is basically a collection of fixes like that. The TS-DDraw project is just a small part of it.
