I have a 486 motherboard that has both isa and pci slot. With Tseng ET4000AX isa card and intel 486dx 33Mhz cpu I got about 9 fps in doom time demo benchmark. I thought that was bit slow, but probably normal. Then I switched the cpu to 486dx4 100Mhz and did the same doom benchmark with the same video card and I only got about 11 Fps in the benchmark. I searched online and others using Tseng ET4000AX card and 100Mhz 486 combination have usually gotten close to 20Fps in doom time demo.
Do you think there is something wrong with the video card or are isa video cards slower on motherboards that have pci slots too?
I just feel like 11 fps is too slow when I tripled the cpu speed and ET4000AX isn't suppose to be the slowest video card. I could be wrong of course, but something feels strange about this.
