Author Topic: Radeon stutter (Read 766 times)

Makarov1 · « **on:** October 17, 2001, 10:11:00 AM »

I have a RADEON 32MB DDR. While playing D3D games, especially in AH, I get brief frame stutters. They are very small stutters but constant and VERY annoying. Has anyone encountered this? I don't have any stutter problems with my GeForce, only the Radeon. I've browsed many newsgroups and several people are complaining about it but no one has an answer for it.

Here are my system specs if that will help:
Abit KT7/RAID
Tbird 1.1Ghz
SB Audigy
384MB RAM

Thanks if you can help.
Mak

Do the stutters occur whenever you fire your guns or Flack bursts around you?

If so, its not your video card, its the hardware acceleration setting on your sound card.

Go to Control Panel and move the slider down one notch, preferabley two, and see if that cures your problem.

Hmm, negative. It happens constantly. As soon as I start rolling down the runway and look out the side window I see the stutters big time. When I'm up high it's not as bad but down low it's really crappy.

Hmmm,...AGP and USB on same interrupt?

I noticed my sound/ vid/USB are all on IRQ 9, but when you go thru device manager you cannot change the number I am running win 2k could this possibly be my problem as well? I get stutters big time and game locks up instantly

do ya have the littel modem light indicator on?.. or anything else flashing in yer task bar?.. that can do it.

Sachs, w2k does this when you have APCI enabled in the BIOS. If you disable APCI in the BIOS ROM BEFORE you install w2k, it will use the standard interrupt scheme.

Once installed, you can get it to go back to the standard interrupt scheme, but it would require me to write a novel on how to do it.

As far as it causing stutters,..it might, but it shouldn't. w2k uses a whole new scheme for sharing interrupts by adding another layer of software to the interrupt architecture to route interrupts to the hardware. It sort of emulates the PCI steering logic in sofware.

Wobble, you nailed it. I have a dang MSN Messenger icon that was causing the stutters. Thanks!

Skuzzy, I had teh ACPI turned off I am doing client build tests with win 2k at work and I test them on my home system as well. I am just curious as to what is causing my problem. I have a tnt2 ultra 32 meg creative labs and a radeon 64 meg SDR card to test it on. I have a sound blaster live value and a mx-400 sound card I have tried all combinations in win 98 and 2000. When I try and lfy in another game such as FA or warbirds I can fly for a bit but then i get lock ups. I do notice some line texture drawings which do not look right to me. Such as drawing lines of different colors off the wins and such. I have a new hard drive speakers keyboard and mouse whihc wil be here tomorrow. ONly thing left to replace are the processor, Mboard (which is almost new)and CD-rom everything else is new as far as apps runing I have yahoo messenger and AH. STill lost on this one.

Via 686 chipset is notorious for having problems with interrupts.

Make absolutely sure that neither your NIC OR SB LIVE! is sharing an interrupt with any other peripheral, especially your RAID controller!

If your system seems to share IRQ on all devices, you indeed have ACPI on. Read more about 686/live problems and removing ACPI from www.viahardware.com

I had a world of trouble setting up my KG7-raid system, it just wouldnt work untill I got rid of each and every IRQ conflict I had in the system. Also there is a small patch which is supposed to fix all 686 related problems. You can download it from www.via.com.tw.

And yes I run w2k too.
AH symptoms were choppy fr, blue screens, ctd, you name it.

Via patch + ACPI off.. smooth as silk, now even overclocked to 1564Mhz =)

Ripley just got off with the tech guys, and they say t write zeros to hard drive. I was getting this error when I would try and reinstall win 98. SO I am going to try the patch first and then if that fails I will write zeros tothe disk. This is very odd system was running great up until 1.08

Sachs: I'm afraid formatting / filling HD with zero's won't do squat to your problem with irq's. If your problem is ACPI, just do a simple reinstall pressing F5 on 'press F6 to if you need to install any third party scsi.. ' and selecting standard PC (w2k)

Make sure you don't have any peripherals in the first pci slot, or any reserved slot for that matter. Consult your motherboard manual to see which interrupt is being used and to which pci slot it corresponds.

Your whole problem might be fixed by physically moving a couple of your components (NIC, Soundcard) to another slots (if running W98, no acpi..)
