Thanks again guys, your input is really appreciated :thumb:
I don't hope the lottery story is true as the store where I bought the TV was not very willing to take the TV back.
About sitting to close, I watched the picture from a greater distance and it helped to get rid of the "stairs effect" of lines. When sitting so close (about 1 meter) I do expect to see some hooked lines just because the resoultion is relatively low for the size of the screen. I did hope for a slightly better result with AA, but maybe the new card will improve that. Otherwise it si not that big of a deal.
The thing that doesn't dissapear is the flickering and shimmering textures. In GTRE it's worse then in GTR2, but on a green border there shouldn't be black "artifacts" kind of things flickering around like crazy I would say. Also I see trees in the background flickering in both games. Also the shimmering of the fences and the poles of the signs for example I think should not be there, this much at least. All of this is is worse in cockpit view then in tailcam.
I did read about similar problems in rFactor and there they made changes to some files from the game that solved the problem. I didn't find this for GTR2/E.
I made some pictures to show that the picture is actualy pretty good, even from a close view. GTRE is not running correctly at all anymore, I think something went wrong when I was fiddeling too much, maybe with nhancer. I guess a re-install is necessary.
Please believe me that the real picture is actualy pretty good, sharp, nice coulours and no noise. It's not easy to take a decent picture from the screen I noticed now.
In the final picture I see some of the trees in the background flickering, even when not driving. The signs are pretty ok when standing still, but in GTRE its worse unfortunately. In general when driving there too much flickering going on in the distance mostly and specific parts also from closer view.
I've read in some places that the Ati card should give better pictures and better AA. I will try that but considering that people who are using the same card as me now I dont have high hopes.
My system is a C2D E6600 2.4Ghz, 2GBRam, Asus P5b. The pictures are taken with the 7900GTO card cause I took out the 9800GT for return. The problems are the same with both cards.
Regarding settings I tried a lot, both on the TV (100hz, sharpness, brightness, colours etc, 720p, 1080i, 1080p, VGA, HDMI) as on the card (AA, AS, AA Transparancy, Mini maps, Vsync in both the control panel as nHancer). I am sure I didn't try all of the possible combinations, but a lot for sure.
At the moment I run 1920 by 1080 with 60hz refresh rate, the native resolution of the screen via HDMI.
