Ok now it gets super weird. 12.90 1458 points 40.72 1570 points 56.73 2715 points (native drivers from XP). My guess is that the later driver is detecting the 3dmark executable and doing some shenanigans to effect a higher score. Change the filename of the 3dmark executable and test again... …

Back in the day, the difference was noticeable on Voodoo 2 cards, at least with that AMD optimized build of Quake 2. Relevant Anandtech article . As I recall, that optimization worked best when pairing a K6 CPU with a Voodoo 2. Older and newer Voodoo cards couldn't benefit as much. I don't own the …

Best GPU what i like for AMD K6-III is Geforce3 + 7.76 and maybe 12.90 is also good driver for it, it should have all, Table fog, 8 bit palleted textures and EMBM. You have piqued my curiosity. Can you please run Quake 3 Demo001 at 1024x768x32bpp all options maxxed, first with 12.90 and then with …

Is there any known fix or workaround for this, to your knowledge? (of course getting a different chipset motherboard is an option, but that's hard for me and probably a last resort) e.g. installing unofficial win98 intelinf drivers What you're doing isn't attainable, and you should split this into …

I think a P3 933 and an FX5200 is a good combo, I don't think either will be bottlenecked.

Switching Windows to 32-bit color causes screen tearing when closing or moving windows (visible redraw "tearing" effect). This doesn’t happen in 16-bit mode. I get it that TNT2 Pro is not ideal for 32 bit, but I had one of those back in the day (the entire system is a part-perfect replica), and I …

Thank you. It seems that a hardware issue is being considered here, but my problem cannot be hardware-related, since everything either works or doesn't work on the same motherboard depending on the BIOS version. From what I can remember, it's related to the initialization routines. I base this on a …

Quake wasn't using 'more modern' instructions. Also how quake renders is extremely different from how Doom does it - all the lighting is applied to a surfacecache, and that blob of surfacecache is where all the optimized spans work from. If you want to see that in action for Doom, there's Vavoom. …

The main differences between the original Doom and FastDoom are these (as of version 0.4): How difficult would it be to add CMOV support (and possibly MMX+SSE) to Fastdoom? Hear me out please: Yes, I know this is supposed to be for old machines - but lately you have released new executables …

Kemet is now owned by Yageo Fixed. They bought them not too long ago. Shortly thereafter, they started selling Kemet-branded polymer capacitors.... One could draw the inference that Kemet polymers are Taiwanese -- that would mean decent quality. I don't trust Yageo for critical stuff, but I have …

No, the LMB is not part of the VRM high if it's 6.3V... VRM high is 12V, so only 16V caps are on it. It's part of the VRM low and I can prove it to you -- take a multimeter and check continuity between its positive lead and the positive lead of one of the short Panasonic FL VRM low caps. You will …
