When settings screens fail, it's time to go for the nuclear option: the Console.

As with all tweaking, it's best to switch one off at a time to see the full effect: we recommend going Glow, Depth of Field, Distortion, then Blur. This includes Glow, which shouldn't be a problem for the engine but apparently is, Depth of Field, which blurs the screen past a certain distance and can be a major problem if your graphics card is only just up to running CODBLOPS, and smaller details like whether VSync is on or off. Load in your configuration file and the most troublesome graphical effects can be switched off with a single mouse-click. You can tweak many features via console commands and the built-in settings, but this app from Steam forums user DustinEwan is much easier. 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. With a new graphic engine, we soon realise the high quailty details of a game that fight for the throne of war games.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. Massive amounts of infantry can populate the battlefield and they will be both partners and enemies. This time playing according to our partners is going to be a must if we want to survive. And finally you’ll play as an American doing a D-Day landing, but not on Omaha Beach, you’ll be scaling the sheer cliffs of Pointe du Hoc as artillery with the Army y rock climbing with artillery and machine-gun fire raining down on you. The final mission in the British campaign sends you to the bombed-out houses and hedgerows of Caen, France. You start off as a private in the Russian army and after that we will play several rols, for most of these missions you’ll be fighting in the sand-swept deserts of North Africa alongside the Desert Rats against Field Marshal Rommel’s troops. Call of Duty 2’s campaign will put you in the shoes of a few different soldiers fighting for different Allied factions.
