i have an i7 CPU and have been frustrated with use of the develop module - when i click and hold on a slider, such as exposure, it takes 1-1.5 seconds for each update to be shown on the display. It makes it very difficult to make adjustments due to having to move the slider, wait for results, overshoot, go back etc. I noticed when I am moving the slider, only ONE of my eight cores is being used. it is at 100% where the rest are at under 2-3%.
i am running win 8 RC 64bit , but if memory serves, this was happening on this machine when i was running Win 7 64-bit machine. Can someone confirm this is the current behavior, and if so , why can't these processes be multi-threaded? We are talking about significant performance boost here.. ''
All latest updates for windows and Video card (tried beta drivers also) I have a 7770 video card 1GB video card, 16GB Ram, photos and catalog are on separate solid state drives.
I was excited that 4.1 was listed to address performance issues with development tab. Strange thing is prior to version 4 the performance was not nearly as bad. Photos were converted to v4 lightroom from v3 (no ! is shown.)
Any ideas? I paid for the upgrade, and features are better, but performance is unacceptable. I have ninja IT skills (IT Architect) so let me know if there is anything I can provide to help diagnose.
