![]() Very interesting but not unexpected results. Later DOS games rarely have speed sensitivity issues. It should also be noted that all of these games were made well before 1995. For the most part, both cards need the system to be slowed down to work correctly with these games. So, on this system running at full speed, the ESS card behaves the same as the AWE64, with the exception of Prince of Persia. If I disable L1 cache via SetMul, then digital sound in Dyna Blaster and Prehistorik works fine. Prince of Persia - music works, digital sound works.Golden Axe - music works, sound effects play through the PC speaker (expected behavior?).Lemmings - music works (game doesn't have digital sound effects?).Prehistorik - music works, digital sound doesn't.Dyna Blaster - music works, digital sound doesn't. ![]() Joseph_Joestar wrote on, 11:01: And here are the tests with my ESS 1868F on the same AhlonXP 1700+ System at full speed: Īnd here are the tests with my ESS 1868F on the same AhlonXP 1700+ System at full speed: Titus the Fox (CQM - proper speed ~ 486SX-25) ![]() I was actually surprised that, at this speed (~ Pentium 133 equivalent), with the AWE64, it was still able to detect the FM chip (albeit with missing sound samples).Ġ8. If CPU speed is greater than that, it's either missing quite a few sound samples (as shown here), or simply reverts to PC Speaker. Titus the Fox (CQM - speed sensitivity issues/missing sound samples) - this game usually initializes the sound properly only with CPUs slower than 486-DX33. Indiana Jones and the Fate of Atlantis (CQM)Ġ7. Prince of Persia (PC speaker - speed sensitivity behavior)Ġ4. Just in case anyone is interested, here's some AWE64 Value CT4520 samples that I recorded in the following games ( you can find the playlist here):Ġ1. One thing I like about this card, though, is the fact that the PC speaker input works properly and sound can be heard in both the left and the right channels (as opposed to some cards like the ES1688 that for some reason redirect the PC speaker to the left channel only). All in all, I would much rather have an OP元 or ESFM card and enjoy all games with proper sound (FM synth). Here's a sample with this behavior when it occurred in Duke3D.Īfter testing almost 20 games (again), I would say that CQM can be tolerable in some games, while (for me) being unbearable in others. Furthermore, even when the CPU speed is lowered, the card (or its drivers) tends to behave erratically when launching multiple games in one session without rebooting (after running 5 - 10 games, I was experiencing weird issues with games like Duke3D, Lion King, Jazz Jackrabbit that were refusing to properly initialize the sound or simply crashing altogether upon rebooting, the games ran fine). in my case, on this platform, even Prince of Persia refuses to initialize both FM and digital sounds and reverts to PC Speaker sound, unless I get the speed below that of a Pentium 100 - 133 MHz). When it comes to speed sensitivity, yeah, it's pretty much like I remember it. ![]() So, in the meantime, I plugged the AWE64 (CT4520) in a VIA C3 Ezra-T/440BX build that I have on my desk. I've just tested the SB16 version with the AWE64 and it works fine (once the speed gets below ~ Pentium 100 - 133 MHz). I've attached the ones that work for me (for SB PRO and SB 16). Yeah, there are a bit TOO many variations of this file, I've also had to search quite a bit to make it work. If there's another version than I can try, let me know. I'm not too familiar with the different variations of this file though. I used the CT-VOICE.DRV which comes with the AWE64 DOS driver (found in the C:\SB16\DRV directory).
