@gustarballs1983 I don't know why I set the caches so high (it's been a while) but I know I did it on purpose. In any case, please let me know what values for sound and art cache you settle on. I seem to recall reading a while back that sizes of something like 4mb for audio and 8mb for video worked well on the DOS version? @gustarballs1983 Anyway let me know what values work best for you. And please do send me any versions of fallout.exe (DOS) you have, so that I can compare to mine.
