My laptop can not run oblivion with HDR on. It gives me a gray screen but the HUD still appears, It works good with bloom lighting with very high settings.


My pc specs are:
Intel core i3 cpu m370 @ 2.40 GHz
6GB of ram (5.80 is usable)
Intel HD graphics

HDR doesn't work natively on Intel HD graphics for Oblivion. You need a modified d3d9.dll file in order to get it to work.

Do you know if it will work with oldblivion?

OldBlivion was rather specifically created to allow nVIDIA's "FX" generation to play the game. Intel products are hit or miss whether you can sort all of the many problems they represent.

I think Oldblivion would be a lot worse than bloom lighting on high settings.
