DiRT 2 Demo Native Surround Gaming

[Robobandit]

I gave up AA and was able to fit in post-process high.. I get 33 min and 39.9 avg at 5760x1080..

post-process high enables the high quality HDR lighting that is only possible with DX 11.. the effects are rendered at full resolution rather than the 1/4 resolution they use in DX 9 mode, so really DX 11 is doing 4x the work of the dx 9 codepath. AA has a far bigger hit with post processing on High than it does on Medium.

here's a good article on the difference between DX 9 and 11 and what they do in the demo -

For me, the visual fidelity increase from 9 to 11 is significant enough for me to deal with the framerate hit and loss of AA.

If you want to force Direct X 9, look for this line in the hardware_settings_config.xml in My GamesDirt2Hardwaresettings



Set that to "True" and start the game and it will run in DX 9 mode. You'll be able to have ~ 60 fps at 4x MSAA in DX 9 mode.

I tried to turn off AA and my FPS did not change on the in game fps meter but probably game needs a reset or that meter is not accurate.

I dont think with full native that AA is needed probably but also I didnt think it would really be much of a performance hit. I guess I need to FRAPS it and see.

Looks like I will need to overclock to get your numbers since my res is a bit higher.

It takes it a few seconds to recover framerate after turning off AA.. exiting the game and going back in will probably help.

Maybe it is just me, but I can't get fraps to work in DX 11 mode, otherwise I'd take a benchmark.

edit: there's a newer version out than what I had.. I'll do a bunchmark run of one of the tracks and post the results here.

2x AA -

Frames, Time (ms), Min, Max, Avg
3007, 84062, 22, 40, 35.771

0x AA -

Frames, Time (ms), Min, Max, Avg
3277, 84936, 28, 43, 38.582

I think the minimums might be off because the second run was with no AA and had the textures loaded already.. it definitely gives a bit more performance, though.

edit 2:

4x AA -

Frames, Time (ms), Min, Max, Avg - First run
2721, 87554, 12, 38, 31.078

Frames, Time (ms), Min, Max, Avg - Second run
2553, 89849, 7, 39, 28.414

minimum framerate is where AA really kills, it looks like.. I've only got a core 2 duo @ 3.2Ghz, though.. the story may change with an i7 or similar cpu.

The sweet spot for me is 0x AA with everything maxed.. looks incredible (especially in replay mode) and driving too fast to notice any jaggies.

final edit: forced dx9 results -

0x AA -

Frames, Time (ms), Min, Max, Avg
4673, 90316, 43, 62, 51.741

2x AA -

Frames, Time (ms), Min, Max, Avg
4060, 83298, 41, 56, 48.741

4x AA -

Frames, Time (ms), Min, Max, Avg
4026, 84781, 40, 53, 47.487

Couldn't help myself.. replay screenshots from DX 11 mode everything maxed except AA, which is at 0x AA -



As you can see by the picture below, I haven't got the hang of driving yet..

[ViciousXUSMC]

We should race :D im totally noob too I can barely stay on the freakin course esp rally mode.

I hope the kiddies are good for me so I get some drive time in today. I think this game is good enough that I can stick with it until I am good without getting bored.

Whatcha talkin' 'bout?! You're an expert next to me, I crash into walls, trees, other cars and the like.....ain't no comparison at all! :oops: I had a lot of trouble with the race in London, I find myself spinning out, drifting outta control....man, it wasn't pretty, nosirree! :cry:

Yeah thats a lot better than me lol, I lose control often you seem to keep control most of the time and the one part around 1:45 when you were about to lose it you got it back. When my rear end starts to go and I find myself counter steering one way and then the other without fail it always leads to a spin out. Have not figured out how to recover.

So does anyone here have SLI'd 5800 series cards that wants to give up a code for dirt? ;) Or maybe someone thats Anti-Steam.

*Cough*

I found just that :mrgreen: namely a guy with two Ati cards and wishing to get some cash back by selling one coupon. So keep your eyes peeled folks, it actually happens !

[McKie]

I actually have 3. I took 2 cards back for replacement. And have 3 codes. Left

Where do you set the HUD to be in the central position? I can't seem to find that option?

[scavvenjahh]

It should be automatic... The game seems to divide the screen area in three in aspect ratios higher than 16:9.
How's your HUD ? What's your resolution ? Are you using Eyefinity with Bezel Compensation ?
