I have a problem with Oblivion. If I enable HDR, and load/start a game, the whole screen is blank (gray/black). The HUD/Menus are still there, I can move, the Inventory shows my model correctly, but everything is blank. I can't see anything. The 3D part is completely missing.
I have read that this happens on Nvidia cards, but I already have the Nvidia Black Screen fix and it doesn't work.
Hardware : Asus EN9800 GTX with ForceWare 175.16 on Windows Vista 32 bit Ultimate
This happens on normal clock, underclock or overclock.
This blank screen does not occur with HDR turned off. But everything looks like garbage without HDR.
