I currently have a 2 second lag from the time of pressing space bar to start playback and the time the aactual playback starts on my screen. I posted about this before and we couldn't really find a conclusion, so I'm wondering:
Do you think getting a new card can significantly improve this? Currently a GTX285 nvidia. Yes, premiere does support cuda(i think that's what it is? or mercury playback or something) on this card.
From your other thread it looks like a more fundamental problem. Give the details I requested from CPU-Z Official forum , http://www.piriform.com/speccy plus the screenshots from http://technet.microsoft.com/en-us/sysinternals/bb896653
Actually, all systems (and yes, even the very fastest systems on the market) will have some lag between the time of pressing the space bar to the time that playback actually starts. This is because the launch is done entirely in software. And slower systems will have even more lag than faster ones.
