- What make/model video adapter do you have?
- What is your computer's CPU speed?
On 'good' graphic cards openGL is close to the same speed as DirectX, but on lower end ones it unfortunately performs a LOT less.
Especially if you have one of the 'cheap' setups that use an basic integrated video card rather than a seperate AGP or PCI Express card, performance is often less than stellar...
(The game I'm working on now gets between 1400 and 1600 FPS on my Athlon 2800+/Radeon 9600Pro, but between 5-8 FPS on my P600 laptop with ATI Rage Mobility)
