Lossless Scaling scales any windowed game to fullscreen correctly without blur.
When you run the game fullscreen at a resolution less than the native display resolution, the graphics driver uses bilinear interpolation of the image resulting in blurring and loss of quality.
Lossless Scaling makes a game window borderless and scales it to fullscreen using integer scaling. The output image maintains its original clarity and integrity. Additionally you can enable fullscreen anti-aliasing in the app even if the game has no such option.
Useful for scaling many old games that do not support modern screen resolutions or fullscreen mode, pixel art games, modern games, if you cannot run them in your native resolution and want to get rid of blur.
App requirements are simple. The game should be able to run in windowed mode and your OS must be Windows 8 or higher. Detailed instructions are in the app.
Enjoy!
