|What does Maximum Texture Size do?
If you pick a "Max Texture Size" that causes the game to fail on launch, then you simply need to navigate to the Aces High settings folder (default location C:\Program Files\HTC\Aces High\settings) and remove the video8.cfg file. The next time you start Aces High, you will be brought back to this screen.
|The maximum texture size effects the visual details of the textures applied to the objects in the game.
Unlike video resolution, which sharpens and reduces the jagged appearance of the edges of objects the game, the texture size effects the details within the object itself.
Take note of the differences in the shots to the right using the various texture sizes in the game.
So why not default to 1024 texture sizes and not be worried about any other format?
First, many video cards simply do not support texture sizes this large. Secondly, the amount of video memory required to deal with 1024 textures is enormous.
The performance ramifications are significant due to the raw amount of data required for all the textures in the game. The video cards ram gets exceeded and has to swap textures often. This is referred to as 'thrashing' and is manifested by stutters, pauses in the game, slow load times, just to name a few
Take a look at the differences in 512 and 1024. You will see very little difference. These screen shots were done at 1024x768 resolution. In order to really have any benefit at using 1024 textures, you need to be running 1280x1024 resolution, at the minimum.
Generally speaking, you would need a very high end video card, with more than 256MB of video RAM, to be able to use 1024 textures effectively and only with anti-aliasing disabled as anti-aliasing can quadruple the amount of video ram needed for any given frame to be drawn.
