So while people are in a testing mood, I have a 4k50p 8bit h.264 camera file that i'm sure will play on many people's computers but I was interested in what vegas version/cpu/gpu people have that can't play it smoothly.

Time line playback on Davinci Resolve is 50fps (14%Cpu,30%GPU)

Time line playback on Vegas15 is 2fps (64%Cpu 4% GPU)

Also i didn't update my bios, so i don't think i took the hit from spectre and meltdown patches unless its incorporated into windows and not into bios...

As I understand it, it was fixed in a Windows update for existing CPUs, and then fixed in hardware in later CPUs. Not sure of the exact versions/models for these fixes but the Windows fix was later than Win 10 version 1511, which is what I'm running. The impact of the Windows fix was supposed to be less than 8%, but you never know.

I'm just trying to think of a reason why your rig performs worse than mine in this respect, when the specs indicate that it should be better. What happens if you just disable your GPU? I've had rare cases in the past where GPU acceleration actually degraded playback performance.

4K 50P .h264 and 4K 50P .h265 is totally a different animal. Try the sample provided here by tripleflip18. See how its run on your system then report it back. I would love to hear more about it.

@Former user On my rig (i7-5960X overclocked to 4.3GHz and Radeon HD6970) your UHD FS7 file, at Best (Full):

• VP15 - GPU ON - 40-50fps - CPU 37% - GPU 33%
• VP16 - GPU ON - 40-50fps - CPU 40% -GPU 30%
• VP15 - GPU OFF - 30-40fps - CPU 65-85% - GPU 5%
• VP16 - GPU OFF - 25-40fps - CPU 70% - GPU 5%

Threadripper @4ghz Frontier Edition card. UHD FS7 footage.

VP16 GPU ON Solid not a blink 50 frames at Best/Full CPU 36% GPU 9% not a blink.

VP16 GPU OFF Solid not a blink 50 frames at best/full CPU 63%

VP15 GPU ON. Surprisingly the CPU/GPU usage is exactly the same as 36% and 9% exact same TL performance

I did not bother with VP 15 for GPU OFF.

GPU on 8-40fps, but when its at 12 fps it feels like 1fps, the FPS display in preview shows 8 but there is no way its 12...... so very jerky and 90% of the time its in the under 8fps, cpu usage 18-25% GPU 3-4%

GPU off, 15-50fps drops to 15fps everytime when you pan down and viewing coffee machine, as soon as its back to the wall goes back to locked 50fps.. cpu usage during 15fps 23-27%, when its playing at full speed and looking at a wall its at 7%, GPU showing 3% locked....

so with this file plays better with GPU off for sure.

gpu off and on seems to be same after doing 5 min of testing.... sometimes gpu on can hold 30-50fps at 100% locked CPU GPU 4% locked and sometimes its at 1fps, no consistency whats so ever.

With GPU on though same exact inconsistency but CPU is between 75-100% most of the time in the 100% range though and GPU is 9-11%

So im guessing your 5 year old gpu is doing much better job at helping the timeline. I've went ahead and bought amd vega 64 and should be getting it next week.... i'll let you know how it goes, I was hoping someone with that card would have ran a test but no one seemed to be able to run the tests so i have to be the guinea pig.

Someone with new nvidia 2080 and 2070 run these tests please...

Look on my laptop from signature

Maybe I am not getting the clue ? 🙃

j-v, Do you have the option set to automatically generate proxy files?

Here is an OBS capture (via RDP from another machine so no audio) of my machine 1) using full sized video, 2) using proxy files.

Ok all my previous test the preview quality i had was GOOD Half and sometimes Full (half because almost always there is a slow down at full resolution)

j-v you're in a preview quality, i just tested it in preview and here is what im getting.

Plays it just fine with only 9% CPU and all 60fps smooth like butter. this is with gpu on. BUT Dropped the very next clip from gopro and guess what.......................... even in preview quality full/half its between 1-30, but most of the time in 1fps.

and after typing all that and going back and playing it again now the second clip plays at 55fps without changing anything, simply going to another window and back. so totally lost now......

I can live with preview quality if it would be consistent but previously i thought preview quality looks pretty bad in comparision to good.

I think i need to test new video card and just hold of on editing with this. do you guys think perhaps slow memory 2400MHz is too slow for vegas?

plays better then my, only thing it could be is your gpu. can you really quick do another video going to options and quickly going to settings in general, video, and preview device. i will compare the program settings to my machine and make it similar.

j-v, Do you have the option set to automatically generate proxy files?

Of course, when you have not the newest hardware.
Developers did not build this option into the software in vain, in early days i had to use a script to swich from and to proxy files, this works much better.
Normally I don't need that option because I don't need 4K video and for sure not 4K HEVC.
But for testing I like to prove those things.

Was that quick enough?

Was that quick enough?

def thank you. i had everything same... so only gpu.......

also previous observation where i was able to run my gopro at full fps and only 9%cpu, somehow it was a proxy.... thats why........... so im back to square one and will be waiting for my amd card to arrive. Thanks everyone!
