can i ask how you use these effects ?
Is it an external program and where can i find some good info on it ?

no worries @SarahWalker and many thanks for the explanation !

Hello, I love to use my old cd's to install the games, it adds to the authenticity and helps my nostalgia. Many games also have some form of copy protection that just never got correctly cracked (Dark Omen) and patches don't seem to work for some of them. Whenever i try to install a game from my phy...

@leilei It's a pure dos 6.22 environment and smartdrv is indeed loaded with expanded memory, mouse and cd driver loaded (Phil's computer lab setup menu, i added smartdrv /x) The hitching is indeed less with smartdrv loaded but the issue of the cpu cache slowing the emulator down in this game still r...

Ok, i was thinking ... (perhaps a bad idea) Some games require less cpu than others so sometimes you make a base machine with a processor in pcem that might be too fast for your own host system to handle. Now i was thinking, is there a dos utility that stresses the emulated CPU to it's maximum so th...

the same thing happens with slower pentiums until they are so slow you land up in 486 territory

OK i just saw the following : PII 233 CPU-cache = on External cache = on result = unplayably slow, CPU 100% PII 233 CPU-cache = on External cache = off result = unplayable, CPU 100% PII 233 CPU-cache = off External cache = off result = unplayable, even worse ! (which is normal) PII 233 CPU-cache = o...

the 486 with pentium overdrive seems to run ok except for some cpu spikes that look like hard drive stutter (but they are cpu spikes)
Weirdly enough i just tried a PII 233 Mhz and disabled both caches in the BIOS and it runs well, just as well as the 486 ones.

i must say not even the pentium 75 seems adequate, when entering the great hall with the large stairs in the beginner dungeon CPU usage on a P75 spiked to 100% again and everything slowed down.

I am now trying a P66 as you suggested.

Yeah, just tried a 486 without dynarec and it plays correctly (albeit a bit slow), tried it with dynarec and it plays the same (a little less cpu time usage). The slower pentiums and the overdrive chip do work correctly but it seems then the hitching is purely a hard drive issue ? It still don't exp...

i shall do so sir

I am sorry for this late reply (i am Serrith but lost access to the account and then real life intervened) I tried very slow processors all the way down to 386 but the same issue persists. I even tried disabling caches in the bios to make them even slower but no success. The problem persists in vers...

No, i'm using a ryzen 9 3900x at stock speed. On a PII 266 in Lands of Lore 2 using 3dfx CPU time is about 60% ( a few hours into the game already) Carmageddon (software) runs flawlessly and that's all 3d as well. (CPU time at 88%) But on Daggerfall it depends it chokes right at the start dungeon, m...

OK, weird thing and it's not v17 related since it also happens in v16 but ... I can emulate the PII-233 at 100% in all games i tried : (even PII 266 and 300 Mhz are rock solid at 100% speed) * Doom * Descent 1 and 2 * Crusader games * wing Commander 3 and 4 * Lands of Lore 2 (with and without 3dfx *...
