I just assembled a new PC using Intel Core i7 3770 / ASUS P8Z77-M / 4GB Kingston KHX memory.

PC connected to ASUS 27" monitor via DVI.

I installed GTR through Steam (I faced this problem with local installation as well)

When adjusting video settings in the game using the HD4000 Intel Graphics, game plays brilliant with full resolution of 1920 X 1080.

Because Intel Graphics HD4000 is not good enough for more modern games (RACE 07 for instance), I installed a SAPPHIRE ATI RADEON 5850 1GB DDR5 to be able to run them on top video settings.

The problem is that the old GTR game is then limited by a resolution of 1280 X 768 and the game is completed degraded in video. 

It is a huge reduction on visuals quality, even using a more powerful and exclusive video card.

I would like to know how to get the ATI 5850 working accordingly on GTR, without destroying the visuals.
