A P2 300 will run maybe 60-70 percent of the games.
A 450 Mhz will run around 90 percent of the games.
Hmmmm..... I have a K6-2 at 400Mhz (128mb RAM) and am having problems with anything but vintage games (PacMan, Galaga, etc.). Part of this may be related to some problems I'm having with the IDE bus but have been too lazy to get serious about resolving (been focused on the cabinet itself). Also, I have a 2MB S3 Virge PCI video card that's destined to be replaced with a 16MB SiS 305 PCI. Can I expect significantly better performance based on the video card?
You can get better performance on older computers by using an older version of Mame too.
Do you have a recommended version (in terms of stability and features)? I'm using MAME32 0.62 under Win98SE. Running in dmame DOS mode does not seem to improve things much -- but I have yet to go so far as to create a bootable partition and tune it to MAME. I like MameWah alot too so I'm a bit tied to windows. I've also been told that recompiling MAME with the AMD switches on helps a little.
I remember first using Mame on my K6-2 300, and then later upgrading to a k6-2 450 and being amazed because that ran "Everything". That same 450 still pretty much runs everything except for a short list of exceptions (which are almost all fighting/sports games anyway, and like there are not enough of those that run correctly on a 450 anyway).
Not my experience (but I'm at 400MHz). I wonder what's different. Contra and similar side scroller games run terrible until I muck with frame skipping and it's still no fun to play. Sound is often choppy (Turtle Beach Montego sound card). Asteroids is unplayable. Columns and Columns II play great but sound is choppy and stutters. I don't try to play much past 1989. Pit Fighter is too slow. Shinobi is OK. Tempest is great (but sucks with no spinner!). I've only really tested Ms. PacMan, Galaga, and Galaxian heavily. I seem to recall StarCastle running crappy too.
What should I be expecting given K6-2 400MHz, 12MB RAM, 2MB S3 Virge PCI video, Turtle Beach Montego AC3D (or something like that) under Windows98 SE? I need a benchmark.
Maybe time to burn down the machine and start for scratch to be really clean and fast about it.
Does this topic belong in "Software?"
