Via Apollo Pro chipset

I have Abit VA6 motherboard , with VIA chipset (AGP 2x ), processor is PIII 600 , 256MB PC133 RAM.

Problem is with very low almost a slide show frame rate at the games(Unreal Tournament).
I hear , that the hard drive is working all the time when playing game.

I have tested these configuration first with ATI Rage Pro grphic card, then I tried with Geforce 2 GTS , graphic card.With no effect.

The same problem is in Win98 se, Win 2k Pro.
I have the latest drivers from VIA-s, ATI , Nivida. And there is no effect.
But strange , with Voodoo 3 card there is no problem.

A tested all hardware , and it is working fine. There is well enough of RAM , so I don`t think the problem is there.I think there is a problem with AGP drivers , because Voodoo3 does not use any special functions of AGP.

I am having similar problems with the VIA KT/KX 133 chipsets also, as I have stated in the 'Tech-to-Tech' section under 'What is the Duron like?'.

I have a sneaky suspicion that it something to do with the power output to the display card through the AGP slot or as you have stated soething to do with the AGP driver sus-system.

Normally the 4in1 service pack (v4.20 or 4.23) sorts the problems out but it is refusing to co-operate on the systems that I have here in the shop.

The problems only seem to occur when running DirectX applications or OpenGl. UNreal Tournament (v4.20) runs fine in software mode, but using any hardware mode, drops after around 45 seconds. The same happens when running Final Reality v1.01 (3D benchmarking software) which it either locks up at the 'Tunnel of Light' or drops back to the desktop at the 'Robots' section.
