Older games with 4:3 aspect ratio are stretched in full screen
This article is considered outdated. The driver settings no longer exist
Many older games that have a limited choice (or no choice) of screen resolution will appear stretched or warped when run in full screen in Crossover 11.x (and up) with a modern computer. A partial list of affected games includes:
Dungeon Keeper 2
Master of Orion II: Battle At Antares
Icewind Dale II
Jagged Alliance 2
Age of Empires II: The Conquerors Expansion
Age of Empires II: The Age of Kings
Heroes of Might and Magic III
Quest for Glory V: Dragon Fire
Grand Theft Auto
Grand Theft Auto 2
Grand Theft Auto IV
Vampire The Masquerade: Redemption
Quest for Glory II: Trial by Fire Remake
Starfleet Command 1
Amerzone: The Explorer's Legacy
Panzer General II
You can always run these games in an Emulated Virtual Desktop (windowed mode as set by Crossover), which you can enable inside Manage Bottles>Control Panel>Wine Configuration>Graphics, but in order to play these games in full screen without stretching, you'll need to make some adjustments to your graphics driver settings.
Note that the following does not apply to Mac computers - only Linux.
With an Nvidia card/driver, use the "GPU Scaling Method" option (set to "centered") in nvidia-settings.
You can also set Option "FlatPanelProperties" "Scaling = aspect-scaled" in xorg.conf.
With an ATI card and proprietary Catalyst driver, set "Graphics processor scaling" to "Maintain Aspect Ratio" in the Adjustments tab of the Catalyst Control Center:
With a KMS driver, run the following command in terminal:
We're rebels. We're misfits. But mostly, we're software liberators. And we're very, very good at what we do. We have to be. Lots of developers work with open source, but only a tiny fraction of those are good enough to get software that was designed for one platform to work on another one. We invented CrossOver software - a unique approach to cross-platform compatibility that does not require dual-boot or another OS license. We launched PortJump to help app and game developers broaden their market beyond Windows® users. And we launched ExecMode to help organizations solve really ugly technical challenges.
