1. Direct X was not included with the install of Windows 7. Why is this? I tried to play Call of Duty: Modern Warfare only to find that I had to install the latest Direct X drivers. This should be standard with any Windows Release.2. I have an MSI 7900GT with 128MB of RAM, during the boot and couple of game screens the backdrop will get corrupted and gets a hatch like pattern. I download the latest NVIDIA drivers for Windows 7 64bit and the issue improved but was not removed.

Valehope - 1.) Odd... According to my installation of the RC, DirectX 11 IS, indeed, included and installed with Windows 7 RC. What version did you install? 2.) Hard to say exactly why that corruption is popping up - but keep in mind this IS still in the Beta cycle and there can still be issues with drivers.

It may be necessary to install the latest DX9-redist (March 2009), too.Mob. AMD64 3000+, 1 G RAM, Mob. ATIRadeon9700, 20x DVDRW, C:XPSP3 (55G),D:WIN7 (25G),F:DATA (250G)
