i was wondering if anyone else that has trouble with their graphics card crashing/ not responding normally has AGP Texture Acceleration enabled or disabled/not available.
i have 4 computers all with about the same specs other then my main computer doesn't have the AGP Texture Acceleration enabled and the graphics card lock's up every few minutes yet on the other 3 computers i have no problems with it and they all have the AGP Texture Acceleration enabled, so is it required to have the AGP Texture Acceleration enabled to play or is it just a coincidence?
While I cannot make an exact comment, you will be better off with AGP Texture Acceleration enabled. This is a general guideline when seeking better performance. In some cases a graphics card will fall into a compatibility mode with it disabled and may not be able to perform the necessary graphics commands for running Spiral Knights.
What graphics card are you trying to use with Spiral Knights in any case? I suspect that an AGP card may be old enough that there could be pre-existing compatibility issues anyway.
