I'm also sending some of my files, if you could upload them to your site and check how CGP works

@Former user Bez włączonego CGP iz pełną głębią 32-bitową (najlepszą/pełną) z wyłączną transformacją widoków i bez CGP uzyskuję 22 fps.

Przy użyciu CGP, wybór ustawienia Vlog i szczegółowej korekty za pomocą narzędzi uzyskujących około 2 klatek na sekundę.

Podaje się, że istnieją określenia, które są określone w postaci graficznej do 3D spadającej po dodaniu CGP (o 30%), a podstawowe CPU podstawowe (~7%), ale nie wystarczające do przechowywania liczby klatek na sekundę.

VEGAS może również ukrytą funkcję użytkową testu liczby klatek na sekundę „tryb profilu renderowania wideo”.
Z powodum raportuje CGP 5,8 fps.
Z wyłączonym CGP raportuje 16 fps.

I also checked mine. 3 fps - that's what I get in the best/full preview haha. I didn't even try to turn on CGP

With your footage @lukizap in 8-bit full mode I get good playback with CGP off. With it on and a LUT added plus some other adjustments I still get over 40fps... most of the time. It seems to struggle to cache frames but if I put the cursor on the timeline and wait a second when I hit play I get a good framerate. Skipping around it's not good.

I don't have any lag of the CGP controls or entering and exiting the CGP on this system (13600K + RTX2080 Super).

The VEGAS benchmark reports 34fps with CGP on and 62fps with it off.

what is the problem, could it be my computer's fault? I think I'll restart Windows. I'm not at my computer now and I don't remember if the panel login for colorization appears with a longer project, it may be that with several files on the timeline the panel can work correctly.

I would reset VEGAS, reinstall GPU drivers, and if that doesn't help just try to work around the issue for now as the cause of the problem isn't clear.

Reinstalling Windows takes a lot of work unless you are restoring it from an image.

Also, do you have to shoot 10-bit 422 AVC? 10-bit 420 HEVC or AVC would use your GPU for decoding and that might improve performance.

I would rather not give up 422 to improve work comfort, I would rather change the editing program to one that can handle it.

I have the impression that my GPU is rather underpowered and this may cause problems.

Do whatever you like but unless you are doing green screen, 10-bit 420 should be enough to avoid banding and other artifacts with Slog 3. Do a test both ways and see if there's any visible difference for your uses.

@Former user With no CGP enabled and 32-bit full (best/full) with view transform off and no CGP I get 22fps.

With CGP on, the Vlog preset selected and mild correction with color wheels I get about 2fps.

There seems to be a bottleneck as the GPU 3D usage drops significantly when the CGP is added (30% lower) and the CPU goes up slightly (~7%) but isn't enough to maintain the framerate.

VEGAS also has a hidden internal framerate test feature "video render profile mode."
With CGP on it reports 5.8fps.
With CGP off it reports 16fps.

@RogerS I do get more GPU use when Color grading is enabled but there looks to be a ceiling of 115watts or so, Vegas can't use more GPU. It's very curious, I would have thought you may have had the highest playback given the 13600K and it's high IPC and clock speeds given the poor multicore use of Vegas for CG. A better CPU to drive the GPU. It might actually be that currently Vegas CG prefers 40 series GPU's which is limiting.

@lukizap 32bit CG lut plus CG I only get a couple of frames per second, I have to play/pause/play and then I get 30fps. I think my main problem with your file actually is a lack of multicore CPU, Vegas is using 86%CPU from memory and it probably needs to use more than I have when it initially starts playing the file or moves over an edit point. As a comparison your file only uses 35% CPU in Resolve, and it also plays at 100fps with no lag.

I"M hoping there;s' 3 parts to this new render engine, the decode, the processing and encoding, and the improvements seen so far are to do with decoding, but it's ability to handle 422 10bit at 4K , 32bit processing gets bogged down which is yet to be improved. I hope that's the case. There's still weirdness going on with Vegas though I could play your file at 50fps yesterday, today 30fps.

did you play my files in daVinci? from what you write everything works smoothly there, I think I'll finally break down and register in daVinci, I wanted to do it a long time ago, but daVinci can't be downloaded until I register.

@lukizap used about 1/3 of my 12core CPU with color grading enabled,

Playback is as follows color transform/color grade/noise reduction

I run out of GPU for noise reduction so I half the resolution for playback and then it becomes playable, it would be great if changing playback resolutions in Vegas made such a dramatic difference. This is Resolve Studio, I don't think you can use 422 10bit in Free version

since only the paid version remains, I will have to wait until next year and then I will say goodbye to Vegas after 13 years.

@lukizap They're doing the continuous upgrade thing now, bring in new features with new release but the upgrade of engine is not supposed to be held back waiting for new version release so hopefully color grade and playback improve for you by then.

don't you think that wading into Vegas and buying a new version every year thinking that maybe they'll finally improve the engine makes sense? I consider spending money on version 23 to be shooting myself in the foot at the moment. I've already spent so much money and there's no improvement in use. I don't know how long you've been using Vegas, but I've been using it for 13 years. There have always been problems with it, but I used to think that my computer was weak and I didn't know this forum yet, where people complain just like me.

VEGAS is in a period of rapid development. The audio engine was overhauled in VP 21/22 and the video engine started work halfway through VP 21 and will continue through 22 and beyond most likely.

I'm using 21.208 and 22.93 side by side as they both work but both have limitations. I have Resolve Free and mainly used it for audio edits with VSTs that wouldn't work with VEGAS. I used to use it for coloring but VEGAS is good enough these days.

That said, if the program doesn't work for you why stick with it for another day?

I'm reheating the cutlet. The video shows how much the color gradnig panel lags. I reinstalled the program, installed it on another M2 drive, copied files to another drive to rule out bad drive operation. I reinstalled the GPU drivers, even updated the BIOS. The larger the project, the more unbearable it becomes to work on Vegas. Could the problem lie with my GPU? It's a rather low-end card, but I worked on it in the previous version of Vegas and everything was fine there. Do you have any ideas?
