I'm downloading the Benchmark project to check the results
For now, exporting a project is taking half the time with GPU enabled than with CPU
But my goal is definitely to improve performance for playback
I don't care if my project take 2 hours to be exported, but I'd like to have smooth playback during editing ...
Your investigation is largely correct. The CPU is rather weak (no hyper threading) and is not helped by the GPU for non-accelerated effects. See http://ppbm7.com/index.php/tweakers-page/92-what-video-card-to-use In addition, 16 GB is not much and only 2 SSD's is also the bare minimum.
Thanks for you answer
will then remove the GPU (it still causes me some black screen issues due to driver conflicts at logon) and try to replace my CPU instead ...
Would an Intel i7 4790 or i7 3930 be a correct choice ?
Once again, my goal is to avoid lagging during playback / editing. I don't care about rendering time.
...we do not know what material ,or, codecs you are trying to work with and what your motherboard is. Not all SSDs are alike, either. MANY suffer from poor write performance if they use a Sandforce controller, or, exhibit bad performance when " steady state" is reached, if they are an older model SSD.
Even for just 1080p material, your hardware appears weak......may be time to crush it !
Be aware the newest versions of PPro CC have much better performance than the older versions. This includes the increased use of system memory, the better handling of 4K material, AND the elimination of the old problem of dealing with the 32 bit Quicktime . MOV files generated by Canon cameras and similar 32 bit codecs which used to cripple editing rigs by limiting memory use to 4GB and forcing a 32 bit operation on the native 64 bit PPro. CS does NOT have these improvements.
These days, especially as 4K is becoming more of a standard, a much beefier PC is required. Even with just 1080p, performance relies on : a fast i7 CPU WITH hyperthreading...the more cores the better....the higher clock speed the better, ( over 4 Ghz is best , overclocked with "k" version). System memory of at least 32GB is required...64 is better. High speed storage is a must. Use only the samsung 850 Pro model,or, the less expensive Crucial M550s...they have good controllers and quality memory for video....most others DONT.
The newest hardware is amazing......check out Bill Gehrke's X99 machine on his PPBM8 website...it SCREAMS with the new Samsung SM951 PCI SSD as storage and an overclocked i7 Haswell E 5960X CPU running at over 4.5Ghz with EIGHT CORES!
THAT is what you really need !!....although you can save money and have less, but, still acceptable performance by buying an older,but, recent machine. That approach is not good however as equipment gets outdated so fast. For example, newer Haswell CPUs contain other improvements besides just clock speed that translate to better performance in video editing.
The newest 9xx series NVidia GPUs also offer the best performance compared to older cards...best to go NEW !!
Thank you for the details, and that's sound fun but you're telling me to buy a hammer to simply kill a fly ...
I am an amateur, not a pro
Resource Monitor is telling me the CPU is higher than 95% whereas the disk usage is about 10MB/s max, and RAM consumption is 9GB on 16.
I've pushed further my investigation and I think I have a workflow issue between AEffects and Premiere.
When I import a video clip in Premiere (with sequence matching the clip settings), the playback is smooth
If I import the clip first in AEffects, then import AE project in Premiere, the playback is laggy !
So, finally I have found the issue
There were several points that put my computer on the knees:
- Max bit depth and Maximum render quality were enabled on every sequence (not needed for preview)
- I was using After Effects for the keying (using Keylight) whereas UltraKey from Premiere seems to bring same result with greater performances
- Some effecs seems costly in terms of CPU, like color correction or sharpness
=> once solved, everything goes fine and realtime playback is quite smooth
Hope it may help someone in the future !
