i've never used SLI before... i've got an older laptop Alienware M18x running dual SLI GeForce 460M 1. when i enable it, first i didn't know i had to reboot. do newer SLIs still require rebooting? 2. most non-SLI supported games actually STUTTER, is that normal? for example when in single non-SLI mode l4d2 runs fine... but the minute i enable SLI, it stutters like crazy. are there special beta commands or options i need to enable for all games to run SLI. i know it's ancient by now, i just never got into SLIs after it was introduced, always could only afford 1 single GPU. any tips would be great, thanks!
