Oh, you have the write through version of the Am486DX4. Can you post a picture from the bottom side of your ST3660A please? Which SRAM and DRAM timing do you have in your BIOS? 20201118212026.png 20201118212031.png Haven't done much tuning yet. Enabling the CPU->PCI mem post write buffer seems to …

If you do experience slowdowns or stuttering sound, you will want to lower the PCI latency setting in n the BIOS. it can affect the speed of the game, but that is true of any non-hardware accelerated sound card. If using an ISA sound card, depending on the ISA bus speed and wait states, it can slow …

Hi, To what extent does using a PCI soundcard impact the gaming performance of a system that is also using PCI for its videocard (given that PCI is a shared bus infrastructure) ? Would it therefor make sense to use an ISA soundcard to maximize the performance of the system ? Thx

Seems that other people complained in the past about performance issues with the SiS530 chipset (even when using a K6-2+ CPU). Apparently the solution was to "toggle some BIOS settings" (but it's unclear which settings those were): https://www.vogons.org/viewtopic.php?p=373660#p373660 Not sure how …

Did you try with an 128 MB memory module instead of 256 MB? With the 256 MB memory module you are exceeding the max cacheable area, which can severely affect performance with a non plus K6-2 CPU. Didn't make a difference. But working with 128mb stick now. I did however look for USB settings. Found …

On a K6-2+ 550 MHz & an AGP GeForce 2 MX (with driver version 7.76) I get ~ 40 FPS in Quake 3 at 640 x 480 x 16 (without any other fine tuning). The K6-2+ is typically 15% faster than a normal K6-2 of equivalent frequency. So with a K6-2 550 MHz, I would expect to see ~ 35 FPS, while a K6-2 500 MHz …

This might be part of the problem, actually (especially with a non-plus K6-2 CPU). If you can, remove the 256 MB module, and use a 128 MB memory module instead. And while you're at it, also make sure that "External cache" is enabled in the BIOS. Very few bios options ... there is a read-only entry …

Granted, I never tested any GeForce 2 - 4 cards on PCI (don't have any), but I do have an FX 5500 PCI, and on a Pentium 3 Coppermine 1 GHz I got about 80 FPS in Quake 3 @ 1024 x 768. Of course, that card is useless for SS7, because of the newer drivers, which would tank the performance. But still, …

No Permedia 2 on your List ? If you use PCI Cards you should avoid using 33Mhz PCI Cards at the Same Time or you will kill your Bandwith. (Eg legacy Network Cards.., Ancient SCSI Stuff..)

Quake 3 and Unreal Tournament are not meant to be played on SS7 :) That being said, your benchmark scores seem very low. What frequency is your K6-2 running at? On a K6-2+ 550 MHz & an AGP GeForce 2 MX (with driver version 7.76) I get ~ 40 FPS in Quake 3 at 640 x 480 x 16 (without any other fine …

That driver may be too new. Try version 8.05 instead. Also, stick to a DirectX version 7.0a. Small improvement indeed for Quake3 with the video driver downgrade.
