Hi Excellent work putting this together! I wonder what AI will do in this space over the next five years.

In reply to riotangel. First PC other than my father's green monitor was 166 mjz Pentium with a 2mb graphics card. Man, when I got that 4 MB Monster 3D to play tomb raider and quake on 3dfx hardware; That shit was game changing.

No emulator for Pentium 2/Celeron? Back in the day I operated the Celeron-300A which was easily overclockable to an equivalent P2 450Mhz! Coupled with Monster3D Voodoo 2 SLI it was a dream playing games.

I still have the Voodoo 2 cards slotted in the old casing. The motherboard was changed post-millennium for AMD Athlon XP and it became quite an unstable period for me.

I haven’t tried yet.

I’m on OS X, and I typically just run it through WINE (aka Crossover) as I have little patience for mucking about.

for ‘speed’ you need 4Ghz something to make it go kinda fast…. Basically if you don’t have a K part i7 you’ll never see it go fast.

Have you tried PCem v16? I wish I knew how fast it can be in a 2013 rMBP i7 16GB RAM. I tried it once but I think I did not configure it well, to run Win 98 for some games. It was slow as hell. I am now trying to use a port of qemu for iOS (UTM) and a forked on steroids DOSBox version called DOSBOX-X which is said to have 3Dfx support too. So far on all three I struggle with speed 🙁

In reply to Darkstar. It's a full software renderer (with a recompiler to get some speedup).

In reply to Darkstar.

I honestly don’t know. I didn’t compare 86Box vs PCem, nor did I even really look at the source. About all I can say is that 86Box didn’t compile with GCC 5, and I ended up going to GCC 7. I should have compiled it -O2 -msse -msse2 as I found out that sse2 was required in some bits, but doing -march on my desktop sure didn’t work on this 10 year old laptop I end up using at home…

From a glance it has a codegen back end, so it looks like it interprets the instructions, so I guess it’s a software renderer….

Do you know if the Voodoo emulation in 86Box is a full software renderer, or does it only upcall/HLE the Glide commands to Direct3D/OpenGL on the host?
