Jazz and Bash work for me with no issues on a K6-2. Lotus does not work, and I have not tested the others.

Jazz ist FAR too fast and Bash has no INTRO.

I think you are wrong on both counts, but I will have to check again. Maybe this weekend. Maybe I am just wrong on how fast Jazz is supposed to be? But it felt the same on the raw hardware as on DOSBox.

What K6 system have you tried it on?

K6-III+ 133/400 (66FSB) on Tyan S1590. Btw. every Board has Problems to determine the correct Temperture.
The CPU is quite cool on 133 but the bios freezes the PC because the board thinks the cpu is over 80 degrees.
Other boards behave the same (TX3) the temperature is always wrong.

K6-3 on same frequency is a little faster than your K6-2, so results may differ. Besides video and chipset.

According to that Dyna Blaster should to work good on K6-3+ 133 MHz with chache1-off, cach2-on.

I've tested with my K6-2 (@167, L1 cache off or L1+L2 cache off).

BodyBlows - no Issue, works well!!
JazzJackRabbit - no Issue, works well!!
MonsterBash (Intro) - no Issue, works well!!
TowerAssault - no Issue, works well!!
- Turrican - Do you mean part 2? As i know, part one is only available at C64, Amiga, Atari and some other platforms but not PC. Have not tested part2 until now.
LotusTurboChallange - has Issue!
DynaBlaster - no Issue, works well!!

From my point of view, really a lot of games will run fine on these platforms, K6-2 or K6-3. In case, you have some issues, you can also try DOSbox, or as last alternative you can build a 386 and/or 486 setup...

If i disable the cache these games start but are WAY to slow.

you are right if I am changing the bios before starting the machine for each different game it will work quite good, but this is not usable
and therefore a no-go for me.

Maybe it's not usable for everybody, but i have no problem with changing the settings (L1 and L2 cache) for every game. A reboot, following a fast change in BIOS is normal and usable for me.
Well, changing the jumpers for different clocks, this is not as usable as changing BIOS options, cause you have to open case and overall it takes more time. If you really want to change multiplier more often, the +' CPUs are the recommended.

I know that they work with disabling the caches and rebooting, but I don't like that.
Yes turrican2 the final fight was meant.

What do you mean you don't like that? That's the whole point of the CPU, you can use tools to disable individual caches, such as gerwin's great SetMUL utility.

the rebooting and changing bios values, rebooting...
if it is possible to do it per software, it would be really cool.

There are tools that allow to switch caches on and off on the fly, just by running it from the command line. Works well for CPUs in the range from 486 up to Pentium III (also K5,K6... etc.)
No reboot required at all.

My batches are "cpucache off" game "cpucache on" but this only disables enables the level1? cache, not all caches, right?

Yes, AFAIK there is no software solution that can control the motherboard cache.

Still, I don't see it as much of an issue to reboot the machine.

shouldnt it be possible to see what the bios does when you turn cache off and just redo that in plain dos? should be kinda possibiru

If you're that much against rebooting, and looking for speed sensitive control, then you should look into compatible boards that can use something like SMB from Rayer (controls FSB from the command line), and a VIA C3 Ezra-T (use SetMul from the command line to change multi, ICD, BPD etc. ). This setup has a smoother CPU range, and there isn't a need to disable motherboard cache.

You said this: "If i disable the cache these games start but are WAY to slow."
Now you say there was no such problem.

If there are other people with K6-3+ CPU, would be good if they'd confirmed that games listed by dr.zeissler above work ok and with which settings. Lotus Turbo Challenge is the only from his list with known issues still.

If someone met other games not working correctly, would be nice to list them here.

That would be cool. I just think if it's possible someone would have already done it? And without rebooting? That might be the challenge here.

One point is that disabling just L2 changes the speed only marginally regarding to DOS stuff. L1 has much higher impact and this means it is also more useful. So the tunability by switching L2 is somewhat limited.

Another option however is throttle.com that uses power management features in certain chipsets to slow down speed. As it uses hardware functions it is totally smooth as well as no TSR eating up memory. If one has a supported chipset throttle is always worth a try.

Very true, the internal CPU cache has a large impact. At least on the socket 7 platform, the L2 cache is still quite useful, letting you toggle between 386 and 486 type performance.

Sorry no tests with the 2 Ultra, it artifacts in any 3d game. I can test with my Banshee though, or maybe go way overkill and test with an FX5900XT?
