What old games can you play that have support for higher resolutions?
Ghost Recon 1. The game's engine is still rock solid.
With mods plane scape torment and all the other black isle games
Emulated vidya will have issues since most of the time the engine knows to cull polys from the normally non-viewable area. Rogue Leader on Nintendont does this. Looks very silly, but is still impressive given how efficient they were.
