So I'm running a proper window of Montezuma's Return 800x600 (tried Glide and DX versions, both Win9X versions), locked to 120fps for testing purpose to see where the game speed breaks, G-sync ON in any case.

Tried dgVoodoo with vanilla and all pimped out settings (MS/SSAA...), GPU doesn't even break 10% usage.

Point being, the game is hard locked to 800x600 max and no mod/patch exists.

However, LS offers LS1 and FSR1 upscaling which IMO should be a bit better than "old-school" stuff dgVoodoo offers.

Problem is the moment I use LS to upscale it's own FPS counter shows inconsistent ~70 FPS, and it shows even without FPS peeping.

I've pretty much run thru most combinations within LS, so I turn here because maybe someone else tried it, and maybe it's dgVoodoo's side that doesn't play nicely with LS?
