    Please elaborate on your system: CPU? RAM? Video Card? Have you tried updating your video drivers? Have you tried closing anything that may be running in the background?

        Can we assume you are able to play other source games correctly? (HL / Portal etc).

        What have you tried already? Can I suggest lowering your detail settings and updating your video card drivers?

        (Also 4.5 GB ? 2+2+0.5 ? Seems like a queer amount for a Core2Duo PC.)

          Apparently the G33 does shading in software (not hardware accelerated; see this). I would not expect very good performance with that. Try turning the video quality settings ingame right down.

            1. update your video card drivers. its provided in the link above, or google the link from

            2. update your NIC drivers

            3. reboot

            4. run a tcp patch or the optimizer from speedguide
   (tweak your network cord)
            if xp, use tcp optimizer.
            if vista/win7, use their patch:

            5. change your desktop to 16bit. try the tweaked autoconfig file as posted in the 1st link above

            6. if you need more tweak tips use the 5 second news link.

            7. turn off all p2p/file sharing while gaming. monitor network use as well, this is a primary cause of lag.

            8. if wireless, try wired or if win7 the tweaks from here:

            if windows disable aero desktop too!
