If you pick a "Video Resolution" setting 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 pixel is the smallest unit which can be displayed on a video screen. Take a look at the 'period' at the end of this sentence. It is one pixel in size.
The number of pixels packed on the screen is what defines the sharpness and/or clarity of images.
The images to the right clearly show the difference the video resolution can make. Notice how much clearer and sharper the image is as the resolution increases.
Naturally, everyone would like to run the highest resolution possible in order to get crisp, sharp details, but most systems cannot handle the amount of work required to generate the data for those high resolutions.
The amount of data alone is enough to slow most systems to a crawl when having to deal with higher resolutions. Let's look at the amount of data, per frame, a system has to deal with.
| 640x480 | 1.17MB |
| 800x600 | 1.83MB |
| 1024x768 | 3MB |
| 1280x1024 | 5MB |
| 1600x1200 | 7.32MB |
As you can see, the amount of data can get rather large. Consider this; every single byte of data must be reviewed by the video card for every frame and you start to see how this can impact the performance of the system. For a 640x480 display, that is 1,228,800 bytes, and for a 1600x1200 display it is 7,680,000 bytes of data per frame.
Now that is just the raw frame data. It does not take into account the working frame buffers, the texture space needed to assemble the frame, scratch pad memory for video drivers, or memory for decompressing/compressing textures. As you increase the resolution, you exponentially increase the amount of work the video card must do in order to create a frame of data.
Another effect of increasing the video resolution is the impact it has on the vertical refresh rate of your monitor. The higher the resolution, the slower this value becomes. Having the vertical refresh rate running at the same speed as fluorescent lights can cause excessive eye strain.
Overall, this is the single most prominent setting effecting the performance of the game. If you find the game runs too slow, then reducing the resolution is the fastest way to get the performance level up.
