I'm just whining about the relative performance of my 7 vs others in virtually every test I've done. My red car render is now at 36 seconds with the latest 19.5.1 drivers. It still is rendering 4K with multiple effects faster than real time. My older i73770 gtx1050ti was about 4x real time in my 4K pipeline so it's great, but not what I believe it should be.

The QSV encoding thing was an interesting find and not sure how it is being used on an all AMD machine.

QSV on AMD CPU? Not sure if this is somehow possible at all.

What MB drivers you have installed? Microsoft or AMD?

P.S. I have render issues with any AMD GPU drivers after 18.5.1.

I have Intel QSV pop up in my render templates on my all AMD system as well, for some reason, alongside VCE.

That's what I thought too, but when I turn that on or off in the preferences my render times change even though I'm using Magix MP4 VCE. Thus the reason for this post.

I have IntelQSV rendering available in HEVC only, but I'm not using that. Just the Magix MP4 VCE variants for all my best times. Now a lame 36 seconds on the Red Car project using VCE with GPU and QSV acceleration enabled in the options.

In my latest clean install of everything to an m.2 ssd, I used the AMD x399 chipset drivers from AMD. Then ran the 19.5.1 Radeon drivers after that and it's slower all the way around though still dead stable and perfectly clean renders.

I dug through all the Userbenchmark tests with an x399 chipset and the Radeon VII. All tests only show at best 135% relative performance for the 7. All the 148-165% relative performance scores are coming from ryzen 7, i7 and i9 cpu mobo combo's. Definitely is an X399 / Radeon VII driver problem it appears.

Still curious on the QSV AMD thing. Seems like a strange behavior.

I don't see anywhere to enable QSV in preferences, only in the render templates next to VCE. It shouldn't even be there, this is an all AMD system.

It is located in the preferences, just under the "Enable legacy GPU..."

Turned it off on my "Signature" rig, with both Vegas Pro 15 (build 416) & Movie Studio Suite 15 (build 157) - was still enabled in MSPS15 - turned off, then re-start Movie Studio - not there; additionally on my "re-furbished" i7-6800K with Movie Studio Suite 16 (build 109).

Yeah, for an all AMD system, or the Intel HEDT (High End DeskTop) systems, QSV enabled ain't gonna' make something work that ain't there! Also, just checked all three with a project loaded and went to the "Render As" - No QSV for any in the Magix AVC or HEVC templates, either VCE or NVENC on my two computers.

Thanks. I've found it in preferences. Exact naming in VP15 is "Enable QSV Encoding and Decoding (where available)". It was enabled (by default). Have not found any encoding profiles where it is mentioned.

Played a little and in my system it does not change anything. Playback and red car render speeds are the same.

No impact on or off on my Ryzen 7 2700x with an Nvidia RTX 2060. Same render times although when its on I do see the option to render using QSV which does render although shouldnt as my setup has no QSV.

Thanks for the notes. I've rerun the test and it appears I must have unchecked 'Allow legacy GPU rendering' at the same time by accident.

Sorry for wasting your guys time :(

So are you saying that by having allow legacy GPU rendering on it sped up your Radeon VII?

I have a 1:52 length 4K project that renders in 1:21 with Magix AVC mp4 VCE with 'allow legacy GPU rendering' checked and 1:54 with it unchecked. The only content in my project is Lumix S1 4K 30p footage, vegas color curves and vegas saturation adjust.

This is interesting as I thought that option just let you use gpu acceleration when using the old Sony avc renders. Might try this with my new rtx

My 9900K renders QSV really fast when BOTH the onboard Intel & AMD VEGA 64 are enabled & connected to screens... Vegas gives me both choices, QSV or VCE, however QSV is much faster. (RedCar sample project = 14 seconds) Interestingly, if I REMOVE the VEGA 64, the QSV render speeds are slower using just the onboard Intel... If I disable the onboard GPU, VCE renders are the same using the VEGA... SO.... apparently there are non-QSV tasks (FX, etc) that the VEGA 64 is able to help with on certain projects freeing the onboard Intel GPU to focus on QSV rendering...

Gonna try legacy on tomorrow with my AMD processor, Nvidia gfx. QSV on just gives me the option to render using QSV which doesn't actually do anything other than regular processor.

Interesting, I will have to test this on mine.

I think vegas should throw up an error, rather than using cpu the way it does. It could also be very helpful for intel cpu people to work out QSV decoding. When you know QSV encode is actually working (rather than pretending to work) then you know drivers and bios etc are all working fine and QSV decode should also be in operation for better timeline performance.

Verifying QSV decode is a bit time consuming when trying multiple options to try and get it going. In a sense you know QSV encode isn't working due to fps encode being so similar to CPU encode but still.. just give me an error, OBS correctly detects QSV not being available when attempting to encode

Not sure if Vegas should throw an error.

However, it would be nice to add such information to Help | About | Computer (all these QSV, NV enc/dev, VCE enc/dec, legacy and may be some special CPU instructions like AVX etc)

Legacy GPU using an NVIDIA card and red car test... No change. Same 21 seconds for me. 64 for CPU rendering.

Theory: Maybe on AMD GFX cards, even new ones it has an improvement due to OpenCL/GL support???

If I am not mistaken, the actual rendering is just the last stage in a chain of tasks which we name maybe wrongly 'rendering'. So any media manipulation as steered by the project + FX and external plugin use comes before the actual render stage, and can use all sort of HW acceleration before the real rendering which will use the specific HW as indicated in the render template. That's why you often see the 'overall render' speed improve when enabling every bit of HW.

The only caveat is that opening up more HW acceleration options to be used together can lead to instability due to SW bugs (driver issues ,mem leaks, race conditions). If you disable QSV in BIOS then you at least get rid of some issues, as well as keeping your CPU cooler so he can perform longer without throttling back due to thermal.

Another annoying thing about QSV is that more often than not you physically need to connect a screen to your QSV Intel to make it work (sometimes needed, sometimes it seems not, it drives me nuts) Needless to say if you have only 1 screen, you would want to connect it to your monster external video card being NVIDIA or VEGA...

Currently I have (2) 4K screens connected to Vega 64 & (1) 1080p screen connected to the onboard Intel for QSV. I haven't had time to find a hack to keep the Intel GPU present in Vegas if I disconnect the 3rd screen... If anyone knows how to do this please let us know...

I reverted back to an older OS image and lost the original Red Car test files...  They are no longer in any of my Vegas ProgramData folders...  Can someone point me in the right direction again?  Thanks!
