To rehash a post i made on AGN3d.com -
I suspected the V3 drivers were the problem with SMP failure in Q3. To test my theory I ran a dedicated server with SMP -
F:\q3test-1.08\quake3.exe +set dedicated 1 +map q3test1 +set r_smp 1
This runs sweet - no V3 interference. I was then able to start another instance of Q3 - this time in non-smp mode and join the server on the same machine! Nice ping...
Can't wait for proper SMP support with V3...
