Here is a problem I've run into that I didn't expect!
When trying to run a 320x240 game on my Samsung SyncMaster 940BF (19", max resolution 1280x1024) the game's graphics are scaled up to the current windows resolution. This of course results in blurring and doesn't look good at all. I've tried toying with the various screen mode options in the advanced settings of the Nvidia control panel, but none of the available screen settings gives me full screen display @ 320x240.
Any workarounds? Would it be possible to zoom the graphics like when you select "full screen preview" in the room editor?
You could try to change the settings for the game and run it in 640x480, or in 1280x960 by using the 2x nearest-neighbour filter. Alternately, to avoid any TFT scaling, you could run it in a window with either of those settings.
Edit: The latter is only available for games compiled with AGS 2.72 and later.
Thanks. I'll toy around some more!
