The Codemasters Forums outline plans for a patch for F1 2010, saying a patch for all three platforms is complete, and they are waiting on approval from Sony and Microsoft before it is released (thanks Eurogamer). Here is a list of some of the fixes in the PC patch:

1. PC 'replay saving' and playback – You will be able to save out the files to replay them later or share them with others.
2. DX11 – The F1 2010 patch will enable the game to run on DX11. All of the graphical improvements are configurable from graphical options when in DX11. Specifically, "ultra" settings for 'shadows' and 'postprocess'. (These options require a lot of processing power, and are only recommended for high-end graphics cards.
3. Eyefinity Support – F1 2010 now supports 3 x 1 or 3 x 2 monitor display setups (minimum requirement of 3 x monitors)
4. Optimisations – We have made better use of multi-core processors in general, which will lead to better framerates on higher end machines.
5. Additional Support - Support for SandyBridge processors, which also adds support for currently available 'modern' processors, like Core i7, which wasn't correctly detected previously.
