What do all these have in common?
In almost all cases, this is the fault of crappy video drivers.
Intel, and S3/Via integrated gfx chipsets have pretty poor OpenGL support.
What? Your intel/S3/whatever works fine with all the other games? Could it be that they are putting most of their resources behind directX , and OpenGL gets treated like the ugly step child?
This game uses OpenGL for a reason, it is the *ONLY* API, that can work on Windows, Macs, and linux (and...) machines.
There are also some commercial games that use OpenGL (Quake series is the most famous), and then all the CAD & advanced visual effect software.
So where does this leave us?
In short, nobody on the dev team has inferior hardware. We have nobody that can debug the issue. We don't have anyone available that can fix intel's / S3/Via's /insert whoever here/ crappy drivers.
We have a mix of AMD/ATI & Nvidia hardware, and if we had any issues that is caused by our code, we would, obviously, try to fix it.
People who have issues with their drivers need to contact whoever the drivers came from, and complain loudly. That is the only resolution you can do to fix it.
For those that have problems, post what chipset or gfx hardware you are using, and what OS, and the driver version.
So far, most of the intel integrated chipsets FAIL/behave badly, on windows, and linux, *but* not on Mac. (Apple seems to write their own drivers).
The AMD/ATI & Nvidia proprietary drivers are better than the open source versions on linux.
