Been playing around with the above recommendations, and things just seem to be getting stranger.
Right now, I'm on another clean install of 98SE with the V5 5500. Decided to keep things simple for now and just go with DirectX 7.0a, Raziel 64's Evolution Driver v1.01.16, and the latest 3dfx Tools -- no updates yet, including the security updates. Everything appears correct under Info in Tools as before, and settings are such to allow use of both GPUs. Installed and ran 3DMark 99 MAX at default settings again, and got close to the same score as before, this time in the 4200s. Swapped out to the V3 1000, made sure the Raziel 64 drivers were still being utilized (just told Windows to install the drive again just to make sure), and ran the benchmark. Approx. 100 3DMarks higher yet again, in the 4300s.
Although these results are basically the same as before, what's strange are the temperature readings -- or at least what can be felt by hand. The V3 uses the same small black heatsink as is found stock on the V5, but with no fan. The chip gets hot as you'd expect. On the V5, both heatsink fans are running, but only one heatsink is getting even remotely warm when in use. Decided to try a game, Descent 3, using Glide at 1024x768 with maxed details. The V3 ran just fine (50fps+) on indoor portions and with particle effects (e.g. smoke), but sluggish on the outdoor parts (<10fps), though it was clearly due to a lack of RAM, not the GPU, as it only struggled when trying to render the farthest distances or several objects at once. The V5 on the other hand did just fine in these parts (50fps+), but performed right on par or slightly worse than the V3 everywhere else.
It seriously seems like the V5 is running on just one chip, but all the settings are correct in Tools. It's running at AGP 1x, voltages are correct, everything I can think of to check based on what's recommended here and on the 3dfx Help Page checks out fine. Any thoughts?
