poor performance in doom3 - 7800GT

[MrDudeMan]

x2 3800+
2gb DDR500
7800GT
9npa+ultra
s12-500


using the 81.85s, i set the resolution in game to 10x7 with ultra high details & textures...

there is no slow down in frame rate, so i guess it isnt really performing poorly, but there is a weird "wave-like" glitch. it happens whenever i look at most textures or when im just moving around. it looks like it is having some sort of overlay problem, but the FPS is great and everything looks swell.

id like to turn up the resolution since i have a 2005FPW, but i need to first figure out why there is a weird wave/overlay issue. its hard to describe...

should i use a previous version of drivers? btw, ive got the nvidia image settings on performance. i had it on quality but it did the same thing. id like to put it on high quality, but like i said, one thing at a time.

I dont know, but how are those fans?

lol

they are pretty good. i cut the wires and put them on 12v instead of 5v...still very quiet and move a ton of air.

the antec case fans are surprisingly quiet, however. they move more air, but you still cant hear them when the case is all buttoned-up and tucked in. the only thing i can hear is a slight, combined fan noise from all of the fans together, but it is basically inaudible.

idle @ 32C
load @ 43C

If it's the same thing that I had happening to me, it looks like the textures split into different sections on the screen temporarily? Like mis-alignment or something.

I guess it had something to do with V-Sync, and turning it on fixed it. It was something about it was trying to redraw frames too fast for the refresh rate or something similar.

turn on Vsync, it should help with the image problems

 

[MrDudeMan]

ahhh that definitely sounds like thats the problem. i cant test it right now but i will try it tomorrow and report back to update you guys. thanks a ton for the suggestion...lets hope that fixes it!

:beer ;

Ultra Quality needs 512MB of video RAM so that's why it chugs. Set it to High Quality and your framerates should jump up. Then check out the Widescreen Gaming Forum fix for Doom3 so you can set it to your screen's resolution of 1680X1050.

You should have no problems running @ that resolution with High Quality.

Doom 3 NEEDS 512 meg? hahahahaahaha ahh i needed a good laugh for today...

i ran it at ultra with my 256mb 7800 GT maxed with 2xaa at 1280x1024 smooth as butter. i could have went up to 4xaa but it wasnt REALLY smooth and 2xaa is good enough for me. i usually dont even enable aa as i dont really mind jaggies.

actually i just noticed that when you change it to ultra it tells you it needs 512mb of video...


when i read that the first time, i thought it said 512mb of system ram.


it actually doesnt have any problem running it on ultra, well none that i can notice anyway. its just that random tearing and overlay issue that seems to be the problem. it might be having a drop in FPS though, and maybe i just havent noticed yet.


jiffylube, thanks for the link to WSGF. i went there to get fixes for other games, but it slipped my mind to do the same for D3.

Im laughing at the fact u believed it needed a 512 meg card, all the 512 meg cards on the market suck (expect the high end quadro's), 7800gt / gtx pwns them all. And the ati x1800xt isnt out yet

grow up. laughing at people for believing a team of progammers and engineers isnt actually funny at all.

yeah it is , doom3 isnt exactly on the same level as fear or anything.

 

[BlingBlingArsch]

but laughing at other ppl seems to be right on ur level.

I think it's actually better looking... It's just not a fun game, somewhat unlike FEAR.

It doesn't "need" 512MB of RAM in the strictest sense, but if you read the developer reports, they say that Ultra quality uses up to 300-350MB of texture memory. Because of this, on some of the bigger levels, you get framerates that are about 50% lower than they should be just because it's using more texture memory than on-board video card memory, so it needs to use some system memory and do swapping. It also quite frankly doesn't look much better than High Q at all.

HQ fits fine in a 256MB buffer, so framerates stay high all the time, and it is the setting of choice on all 256MB cards, unless you want to be handicapping your card for no reason.

Cheers! :beer:

Ultra is pretty useless anyhow ,if you take some screenshots in ultra vs. high you'll see that theres very little differance at all and in most cases you wont see any differance.

Also if you want an improved framerate bring down the console and type com_fixedtic 1 , This command adjusts the overall speed of the game depending on your monitors refresh rate but at the same time gets rid of a lot framerate fluctuations associated with Vsync, 60Hz refresh will run the game at normal speed but if you use 85hz / 100hz etc. it will run faster than normal. personaly I like running it 75hz which gives the game a slight speed boost and runs extremely smooth. Vsync must be enabled for this command to work correctly.

Dude I play doom 3 on my 6600GT at ultra quality, with everything high, and at 1280x1024, and I have 128mb of video ram. You do not NEED 512 mb, sure it may get you 5 extra fps, but are you really ever going to notice that little difference?

Im laughing at this statement...LOL!!!!

 

[MrDudeMan]

thanks for the insight everyone. unfortunately, i sat down to play and start messing with these settings and the PSU started smoking!!

the computer is less than a week old everyone say a little prayer for me regarding the death of my PSU and hoping it didnt bring anything down with it. i want it back so i can start playing D3 again!
