Thanks for reply
i got an i7 4790k 4.0ghz, gforce gtx970 4GB PCI-express 3.0, 32GB DDR3 mem, 2x 250GB ssd HD but still davinci don't making good performance, thou i notice ver. 12 have some new stuff improving the editing prosses. Still new to me so havent tried it much yet.
When looking at the resourse usage i see that CPU working at 2-5 %, MEM use is about 20-25 %, and GPU 1-6% when editing and would expect it to working harder comparing to how slow DaVinci prosess the vids.
The only solution i found was to cache the vids (Playback>Use optimized Media If Avaiable), but as i said havent tried it out much yet.
Im still a newbee in the field so If anyone have some tip how to get Davinci run more smoothly in the editprosess it would be much appreciated also tip in the hardware configurations.
