Hardware requirements
From VDrift
VDrift requires a relatively fast CPU. A 2GHz or better clock speed is recommended, although you may be able to squeak by with a 1GHz or better CPU.
VDrift requires a recent NVidia or ATI graphics card. A Geforce 7 series or better (or the equivalent ATI card) is recommended if you want all visual effects, although you might be able to get by with a Geforce 2 or better. Intel graphics cards are not recommended and are not supported. Make sure you have the latest drivers and can run other OpenGL applications.
