By periodic slowdowns I assume you mean it'll run great at a high frame rate... then 'stop' for a second or so, then resume?

That's the infamous ATi stutter...

Try reinstalling DX and the ATi driver... preferrably CATALYST 3.0a.

i dont think that will help becasue i did get my video drivers reinstalled but it still did it...note this was some time ago but still
do you have any other suggestions...i will try that one soon if any others dont come in...note i mean suggestions

There doesn't seem to be any 'direct' solution.

All of the suggestions I can possibly give short of reformatting:

• Reinstall or upgrade to DirectX 9
• Reinstall or upgrade to the CATALYST 3.0a drivers
• Go into DXDiag and lower your video hardware acceleration one notch
• Change your AGP Aperture size and/or AGP transfer rate
• Enable or disable AGP Fast Writes

I Fixed It!

I changed the AGP in the BIOS to

AGP Aperture Size: 254M
APG Mode: 4X(note only some motherboards support this)
AGP Read Sync.: enable
AGP Master 1 WS Write: enabled
AGP Master 1 WS Read: enabled

those are the only cahnges that i made and i tested the Rom after each one for Optimal Performance. Its mostly the Read Sync. that did it and the Aperture size too.


now i can finally play Goldeneye with almost no jerks

There is no 'infamous' stutter that affects the Radeon 8500. There might an issue with the 9500/9700 but i dont have one of them.

All my DirectX and OpenGL stuff is perfectly smooth and the only pausing in Project64 is from the bug introduced in PJ641.5. Switching to D3D7 1.4 fixes it perfectly.

This is with Windows XP Pro, Catalyst 3s and DirectX8.1

Oh and if you're having trouble with Goldeneye then use 1964 as it runs it much faster than PJ64.

Lucky you that you haven't experienced it, but trust me, people were complaining about stutter before R300 was even announced.

When the Radeon 8500 was first released there was a pausing problem that affected OpenGL and D3D, along with another bug with multitexturing which made the FPS drop from say 100 to 20, but they were fixed a long time ago (and i mean at least a year ago).

Yup, and guess what, the stutter is baaaaaaaaaaaack...
