I can't remember where I read it (because I read a protected mode list also, and game producers comment on this a lot) but I'd read where the MMX instructions are not proving to be any real help there. Exactly how much L1 cache is on the PPro 512K L2 chips vs. the PII 512K L2 chips, do you know? > > The huge gotcha in all of this is that the PII only caches the first 512MB of > memory. > > > -- > John > dyson@freebsd.org > jdyson@nc.com > > ----------------------------+----------------------------------------------- Chuck Robey | Interests include any kind of voice or data chuckr@glue.umd.edu | communications topic, C programming, and Unix. 213 Lakeside Drive Apt T-1 | Greenbelt, MD 20770 | I run Journey2 and picnic, both FreeBSD (301) 220-2114 | version 3.0 current -- and great FUN! ----------------------------+-----------------------------------------------
