ATI Rage 128 Ultra 32SDR and OpelGl issues

hi i have a Rage 128 ultra 23mbsdr on an Athlon 1.0Ghz with 256mb ram running on Windows XP Pro.
i have problems running OpenGl games on this card. for example in Counter-Strike the game jerks while running on 1024768 on opengl).
I also have a TnT Vanta 8mb Agp and Counter-Strike runs perfectely on that in OpenGl on 1024
help needed.

I’m sorry to be the one to tell you this: This card is ancient. If i were you i’d buy a GeForce 4 Ti or a Radeon 9700. If you’re short on cash, try a Geforce 4 MX or a Radeon 9500.
