I confirm that on a Socket 7 Pentium machine disabling L2 cache has almost no performance loss (10% max) due to the RAM being practically just as fast. But with faster CPUs like Pentium III the L2 cache has much more significant impact. The later cache levels are slower than the ones that closer to …

OPL2 (Adlib) and OPL3 sound is an essential part of DOS gaming. In my opinion if one bothered to assemble a retro PC for DOS gaming, having a correct sound for the period is important. Sound Card and CRT Monitors have the most noticeable impact on the experience because they were the the medium …

I was obviously joking because I thought you were. The AWE64 is very good for what it does. Of course it would be nice to have it all in one card, but we already know there is no such thing.

The competition was stiff between 1988 to 1993, every year was a new revolution in ISA sound cards mainly by Creative. It would be interesting to know what strategy Adlib planned to compete with the Killer Card. The timeline shows no new products by Adlib from 1987 to January 1992 when Adlib Gold …

Each run is randomly different? Some corruption creating a random bottle neck in performance. Try different RAM and make sure you don't go above the cacheable amount of the Motherboard. If it doesn't solve the problem try changing the CPU. As you disable the Caches the CPU relies more on the RAM …

2910 is non-PnP, 2950 is full-PnP. Plug and Play = setting Address, IRQ, and DMA via software. Non-PNP = settings via jumpers. No difference in sound quality. Both have the hanging note bug. Both have clicking DMA bug. The CT2910 has an YMF289 OPL3 so it is slightly preferable. The CT29xx series is …

Sounds fantastic, right up there with the Sound Canvas. Hopefully the price is around 80 euros as the X1 was.
