Doom 3 running a bit jump on a 6800GT

[VigilanteCS]

Hi,
My dad recently got a new computer, the specs are:
AMD Athlon 64 3500+
Asus A8V Deluxe (socket 939)
1 gig corsaid XMS pc3200
80 gig SATA Hdd
eVGA Geforce 6800GT

My problem is that doom 3 runs a bit jump all the time, on any resolution. The framerate doesnt slow down, it just jumps. If you are intense into the game you'll basically not notice it, but if you walk sidwats looking at a wall youll notice it jump. It's pretty consisten. The weird thing is that far cry runs fine.

Any ideas? I've tried turning vsync off and that didnt help.

Thanks a lot.

1T command rate enabled? Using dual channel 128bit mode? Fastwrites and sideband addressing enabled on your AGP? Check these and see.

#1, I dont know what 1T command rate is, if the by 128 bit dual channel mode is with the ram, I don't know, how do i check? I'm not sure about fastwrites and sideband addressing...this is my frist Nvidia card and I only knwo where that stuff is for ATI cards.

stop pressing the space bar then

JBDan, any help?
Also, i'm running on nvidias latest drivers, are they the best for games?

Could be AA filtering, could be an EAX sound function enabled on your sound card software, could be a malicious program running in the background, you may also need to defrag the sata drive.

Could you perhaps maybe try to figure out when these jumps precisely occur? Maybe during a sound or just before a cut scene? Perhaps when there is a heat effect from a gun or missile?

 

[JBDan]

66.93 drivers? Yes they are best whql certified but best performance? Thats up to you and taking the risk on BETA drivers. Your talking 1 or 2 fps difference. On your A8V mobo in bios settings disable your "2T command" rate. Use cpu-z ( http://www.cpuid.com/cpuz.php ) version 1.26 to see if your in dual channel mem mode. Also if you have the latest BIOS for your mobo (1008) at the post screen it says "128 bit RAM mode" on the AMI trend post screen. As far as fast writes and sideband I use RIVATUNER to view these settings and they are enabled by default. www.guru3d.com for RIVATUNER

Vigilante:

1. 1T command rate has to do with your ram. Go to bios, find your ddr memory cmos or whatever it's called (where all the timings are located), and you should see your command rates. Make sure it's 1T instead of 2T.

2. I'm really not sure what he said about 128 dual channel mode either, but if he meant video card, go to AGP Apature somewhere in bios, make sure the memory is set to 128. Not sure if this is what he meant though...

3. AGP Fastwrites is also located under bios, if things run choppy DISABLE it.

4. Sideband addressing? Never heard of it.

Hope this helps!

 

[Mrvile]

Well it looks like Dan beat me to it.

PS: Doom 3 is actually a more graphically challenging game than Farcry. Turn off AA and AF and see if you still get jumpiness. Make sure your settings aren't Ultra mode.

My settings:
Video settings - all HIGH
AF - HIGH
AA - 4x
Resolution - 12 x 10

Mine runs fine.

# 2 > 128 bit = DUAL CHANNEL 64bit=single channel.
#4 > http://www.adriansrojakpot.com...AGP_Sidebanding_01.htm
AGP fastwrite is NOT located under bios on the A8V (with rivatuner you have easy access to these settings)
AGP aperture should be set to 256 in my opinion, but there are many debates on this topic!
On the RAM in bios go to >cpu settings>mem settings>scroll to bottem and disable 2T command

I run at same settings as you mrv. Mine runs "good," but I could see room for improvement. This improvement I can gain by turning V-sync off, but V-sync ON plays soo much nicer. I just deal with the occasional "slow down." I'm just too darn picky and want the best FPS with the best image quality lol.

Vile, I'm with you and the VSync. I've played many FPSs with it disabled, but Doom 3 really seems to get more noticeable tearing than any other title. Anyone else notice this?

 

[VigilanteCS]

I notice no vsync is especially bad w/ d3.
I'll try Disable Fastwrites on wednesday (when I have access to that computer, it's at my dads house) Also, the AGP Aperature was set to 64 megs, I upped it to 128 (I didn't have time to test this out, though). DAN - I do remember seeing a fastwrites option in the bios - is this the likely cause?

Regs - the pc is brand new, so I doubt there is any malicious software, I switched to firefox as soon as we got the pc. I'll try disabling EAX.

MrVile, I never ran it with any AA and AF on, I was running it on 1280x1024 on high quality, vsync on.

I'm kind of upset about this, the pc was built by ABS (www.abspc.com). If I could get it running perfect it'd be great..

Try it with Fastwrites on then try it with them off. Sometimes this can make a difference. When you chose high quality settings in Doom 3 it turns AF on by default to 6x or 8x if Im not mistaken.

 

[VigilanteCS]

I know there is an AA option when you go to advanced options, don't remember about AF though. SHould i just shut off AF and AA in the nvidia control panel?

I'm worried about this, I just really hope that this is not a hardware defect becuase my dad shed out a lot of money for this computer.

 

[JBDan]

Put AF and AA settings to "Application Preference" Don't worry it will be fixed through trial and error

 

[VigilanteCS]

Thats comforting to know that it's not a hardware defect, do lots of games have certain quirks like this? Anyway, AA and AF have always been on applicationg preference, but i'll screw around with every option i can find.

Yes games have quirks like this. Drivers can make a "world of difference" and as far as OC settings, drivers are oc dependent as well

 

[Mrvile]

Sorry JBDan about the fastwrites, most motherboards have it under bios but I guess Asus doesn't. For number 2, I still don't know whether you mean system memory or video memory. And changing AGP Apature really doesn't have a noticeable effect on anything, so I just set this to default (128). I clicked the link to sidebanding but I'm not gonna take the time to read all that I'll just make sure they're enabled

Wait, JBDan, how do you "improve" D3 with VSync off, but play it "nicer" with VSync on? Shouldn't it be one or the other? Well, I guess if frame rates are limited with VSync on you can improve by turning it off but you get some tearing. I'm actually not really sure if I have it on or off, I usually go over all the options before I play a game but I guess I missed this one, so I guess I have it at default (on?).

Yeah AA and AF should be set to application preference with the nvidia control panel thing, otherwise you'd have to change it for every game you play.

 

[VigilanteCS]

Well it's a good thing that I'm upgrading my video card and PSU in my pc, so then I won't have to worry about my dads pc =). Currently MY specs are
350 watt codegen psu (12A) <--sucks
Athlon 64 3000+
MSI K8N Neo Platinum
512 mb kingston hyper X
80 gig IDE hdd <-- sucks
Radeon 9600 pro <-- sucks
Would this psu be enough for an x800 pro, 6800 or 6800 gt? http://www.newegg.com/app/view...=17-182-002&amp;DEPA=0
since it's 500 watts and 34A on the +12V rail n all......

Srry? dont worry bout it, your given your advice and thats what these forums are for As far as # 2 the A8V gives a post (if you have 1008 bios) that tells you if you are in "dual channel mem mode" = 128 bit. The FPS with V-sync off increases on my machine considerably, but with V-Sync on the gameplay is much more "cinematic" as this is what v-sync is meant for. Just run aquamark or 3dmark03/05 with v-sync on or off and you will see what I'm talkin about. Mrville how are you liking your system and do you think you can get more out of your RAM?

 

[Mrvile]

First of all, that video card is a beast. Just old.

Anywho, I really don't know much about Rosewill, and in that case I wouldn't buy anything from them. But by specs it looks like a pretty good PSU and all, personally I would get a better named PSU.

 

[VigilanteCS]

like antec, thermaltake or enermax?

 

[Mrvile]

More like: Antec, Enermax, OCZ, Tagan, Fortron, Sparkle.

Thermaltake = ugh
