6800 - problems (stutters, 'hitching') etc ?

[darXoul]

The first thing I'd try would be a BIOS flash. Many people claim that the stutter problem disappears once you update your card's BIOS. I don't know if this is a universal remedy but I'll try it myself if I experience the infamous glitch once I get my Leadtek A400 GT soon.

I had the stutter effect when I got my Leadtek A400 Ultra TDH but the 66.00 drivers fixed everything. The latest BIOS on leadteks FTP didn't help

I did try the 66.00 drivers and I cant update the bios, because i have a GT... there is no bios update for it.

I was thinking of upgrading to a GT but I think I'll keep on reading first until a solution is found. My 9700 Pro is still doing fine anyway for me and all the new games.

Hi. I've been trying to solve this problem since I've put together my new gaming PC last week.

I am using a Shuttle X83G SFF case and mobo. it is a VIA chipset
Athlon64 3200+ (Clawhammer)
512MB PC3200 from Crucial
PNY Geforce 6800 GT

Nothing has been overclocked, yet at 1024 by 768 and High Quality, I get stuttering when I move into a new area in Doom 3. I notice that the system seems to hit the hard drive during the stutter, which usually lasts a second or so. Subsequent play through the area in question runs nicely... so say I quickload earlier in the same section... the whole area plays smoothly as its been cached, I imagine...

I have followed the suggestions offered here and elsewhere.
I have made sure the card is in single display mode.
Fast Writes are OFF ( if i turn them on, it does not seem to make a difference, still stutters)
AGP Aperture is set to 256 MB
Using 61.77 drivers for video card.
Latest 4 in 1 drivers from VIA.

Any suggestions? I am going to try the 66.00 beta drivers next.

I didn't do anything in my motherboard bios or flash my video bios.
All i did was use the 66.00 beta drivers and all my problems with slowdown/nitching/stuttering went away.

I've tried the 66.00 drivers. It helped the problem a little bit, but its still quite noticible. For example, when I run the standard timedemo demo1.demo, the first time it runs, it very visibly slows in the same places to a crawl the first time.

The 2nd time I run that timedemo, it runs smooth as silk through the whole thing, and the fps is at least 10 fps higher than the 1st run.

This is getting rather annoying. I am eagerly awaiting a solution to this.

Try running under AGPx4 instead of AGPx8.

This is normal. It's caused by the MASSIVE ammount of memory swapping and texture reading from the hard drive. Once you run the demo once through, everything gets placed into memory and it does not hit the hard drive nearly as much and thus runs alot smoother.

I think in an anandtech article they said that when they benched they used the 2nd run due to little to no hard drive swapping.

My problem is that this happens in game, not just in the timedemo... whenever i move to a new area. What then is it loading into memory when the level loads? Is it completely unavoidable then?!

well, sucks to be you people. The 9800 pro 256 is still performing fine on current games at full settings. Glad i didnt blow 500 bucks upgrading yet.

Check to be sure no irqs are shared, page file to 2048 (constant size)
Disabled Fast Writes, 1.6 agp voltage, 256 aperture size, PCI latency 64.
DirectX 9.0c + XP Sp2
Asus 1.006 bios Final
Check Video card clocks (both set to 350), No bios update for GT yet.
Upgraded drivers (tried 66 beta, & 65.73)
Latest Via 4in1 driver 4.53
removed audigy 2 zs
new 550watt Antec True control power supply

Still having pauses in Railroad Tycoon 3 (1.04 final). Determined by removing audigy card, that repeating sound during studdering/pauses is side affect of original problem, not the problem itself. (removing all sound hardware did not fix the studdering/pauses)

Possible causes remaining:
Via chip conflict with Nvidia Card (going to put in my intel system later to try)
Keyboard/mouse polling problem - (problem is only evident during games where keyboard and mouse are used, not during non-interactive high intensity graphic programs [pirate ship demo, mermaid demo, dxdiag test square] ) - will try usb instead of ps2.
NVIDIA Driver &/or bios problem (unlikely, problems with all tested drivers so far)
Conflict between games and nvidia system tray programs (unlikely)
Graphics settings configuration problem. (AA, T&L etc)
Software needs now patch to fix problem.

I just bought I a 6800nu and I am having this problem in Doom III. I made a post about in the video forum earlier today. It stutters at high quality only. Medium quality plays fine. I though is was my limited amount of system or video ram, but now it may be something else. I will start trying some of these things tonight.

Seems as though there might be two different issues that people are having. One is a delay with loading video/texture data into memory, and the other is a stuttering of the display during game play.

I am dealing with the stuttering problem. It is noticable on almost all games, but more so on flight simulators than FPSs. Frames per second stays great (>60) but there is a jittering/ hesitation of the display about every 1.5 seconds.

I did NOT have this problem until I "upgraded" to a SB Audigy 2 ZS Platinum. No such issue when I was using the proprietary AC 97 sound.

THIS IS A PROBLEM BETWEEN THE GEFORCE 6800 GT AND THE AUDIGY 2 ZS !! Hardware compatibility, resouce sharing, driver issue, or something else.

I have not had any luck with the fixes mentioned in this thread.
The EASIEST fix is to disable the Audigy 2 in windows....voila !! No more suttering! (and no sound.)

Disabling fast writes didn't fix problem.
NVIDIA driver 66.93 didn't fix the problem.
No conflicts listed in device manager.

Considering abandoning the Audigy in favor of onboard sound!!
HELP!
