For multiplayer, make sure CODBLOPS gets all the bandwidth by right-clicking on 'Call of Duty: Black Ops - Multiplayer' in your Library, selecting Properties, and unticking 'Enable Steam Community In-Game'. If you're only playing the single-player campaign, try running Steam in Offline Mode.

If you're using AMD (ATI) drivers, Steam can update them for you. Finally, double-check that you're using the latest drivers for your graphics card. It's also worth running the Windows Disk Defragmenter application to make sure your drive is properly organised. If your antivirus software has a Gaming Mode, remember to switch it on before starting the game. Shut down any apps like BitTorrent, web browsers, instant messaging tools, Skype type tools and music apps - all of these soak up memory and/or bandwidth that CODBLOPS will want to use. CODBLOPS is a very system intensive game, so before even firing it up, make sure it has as many resources available as you can throw at it.
