When I first built my computer for Resolve in September, it was handling my normal HD files very well. Now, however, the playback is not in RT (it was before), and it takes an abnormal amount of time to save.
Two things have changed that I could immediately think of:
1) Switched from an Ultrastudio SDI to a Decklink SDI pci express capture card.
2) Perhaps CUDA version 4.8.750.0 is not good for the system?
I'm running a PC machine, by the way. Quadro 600 for GUI, GTX 680 for GPU. 16GB RAM. Also Disk Speed Check gave me the thumbs up on everything. Also when I played back the CPU usage was around 22%, and I even tried on ungraded clips. Again, it's very odd that it was running RT, now after a few months it isn't. Should I reinstall?
