The graphics on roblox are pre-rendered, preset settings. that cannot be overridden with your graphic card control panel.
so it is IMPOSSIBLE for roblox to ever improve over blockland's look.
if people's crappy server lag wasnt enough to make me turn away, it was the intense aliasing, and lack of good resolution settings that scared me off.
3D games are beyond rough edges and fuzzy distance lines. if you don't intend on improving away from those, then don't develop your game on the PC, use a stuffty console
