Yes, it has nothing to do with TT RAM, it's about memory detection in
general.
Based on Uwe's latest comment, max gap can be up to largest real HW
video resolution, after that apps like NVDI start to bug i.e. it still
needs to be modified. Because correct gap is needed for memory
detection, but that causes problems with apps, VDI modes larger than
real resolutions will never have correct memory detection unless
TOS will be specifically patched to fix that. :-/
