Hi everyone, my first post here. I'm looking for a guidance on how to make rivatuner work properly on my new Sager NP5125, which is an optimus-enabled laptop. I tried to post this on notebookreview.com, but it's a bit slow to get a proper response. So ,I'm trying to repost what I have on there: I've tried GPU-Z as well. Sometimes when I try to go to sensor tab of my GT330 M, it freezes my system (and I have to restart my laptop). Sometimes it can read the value fine and sometimes the reading stop (but the system still running) Could it be there's no good way to monitor the dGPU of Optimus-enabled system without forcing the GPU to be on all-time in dGPU? Is there anyway I can use RivaTuner + GPU Monitor for my system without having the dropped keystroke problem?
