Not sure how "System Check" exactly was accessed in VP13 but the GPU acceleration options available in "Encode mode" in the VP13 custom render settings have gone in VP14. I don't know why. But that would explain why you are not offered the check.

There is a SYTEM Tab on the "Render As" and in that there is a "GPU Check". This appears in VP13 but NOT in VP14.

Confirmed. I did a render test of a one minute event. It took 47 seconds in Vegas 13 and 84 seconds in Vegas 14.  Same template and same render settings. Could the difference be the new way it resizes the frames? No filters were used. Resample was set as disabled in both versions.

@Grazie -> Go to Internal (hold SHIFT and click preferences), find "GPU", and change Allow GPU Rendering from FALSE to TRUE.

Now GPU check is available.

GPU Acceleration is already selected in Preferences. If, as you are advising that I go to Internal to switch it ON, then I'd suggest that this is a bug.

In PREFERENCES is GPU Acceleration for preview (and processing). In Internals -> for rendering.

Nice find mateuszszar!

Access the Internal preferences by holding <SHIFT> while clicking Options > Preferences.

This really should have been in the release notes.

The question would be if enabling it for rendering makes any difference in render speed. Looking at the GPU requirements, they havent changed at all and I assume that GPU acceleration for rendering just isnt there, like it is for VP13.

Actually I won't miss GPU render support, guess I'll leave it deselected :D

I went to the internal preferences and changed the setting to TRUE and did another test render and it made no difference at all. I am testing with the Sony AVC/MVC (*.mp4;*.m2ts;*.avc) = Internet 1920x1080-30p.

With Vegas 13, there is an option to select and use the GPU. There is no option with Vegas 14.

So am I now stuck with slow renders because I can no longer select GPU? Sure looks like it. :(

I am going to register this thing so I can play with it for 30 days instead of 7 days and give myself more time to see if my money upgrades to this or not. I backed-up my system before I installed this so I can go back to as if it never happened if I need to.

Looks like we have the 'just released' blues...

Got it mateuszszar!

Found it... thanks...

However, since I have changed my video card to RX470 (from Radeon HD5750), I have lost the MP4 GPU encoding ability.

Unfortunately, newer cards are still unsupported. I have GTX1070 and acceleration is worse than my old GTX590!

There is clearly no support for newer cards. Nothing.... I am still stuck with my gtx580 since there is no graphics card out there there ot out-perform it. This is Very very very disapointing....

Intel Skylake is supported in several ways, e. g. for HEVC render and video processing.

Does Intel Skylake also help Mainconcept MP4 encoding too?

Didn't test yet as I tended to disable GPU render boost in former versions. Will test later tonight.

Just to know on what you are missing disabling GPU rendering: Using a gtx580 graphics card and rendering with mainconceptAVC, will render a 60 minute long video in about 32 minutes real time. So, GPU rendering is HIGHLY important.

That means nothing without knowing how long it takes without GPU, or at least telling us the project settings, project content, spec of your machine, render settings etc..

That system tab GPU check on the render templates item was really uninformative.

1. This has nothing to do with GPU usage by the Vegas video engine. That is in system preferences. Always has been.

2. It would list OpenCL or CUDA as available. The Mainconcept AVC file encoders did have OpenCL and CUDA implementations, however it is very well known that they are hard coded to specific GPUs and these are older GPUs and Mainconcept has never updated them for newer ones and given the years of time past they probably never will.

So listing OpenCL/CUDA as available is misleading info given the underlying implementation restrictions. So if they dropped that check button then that is probably a good thing.
 

Sony AVC is the only other file encoder that had some GPU support but it really did not use the GPU for very much and thus got little boost. Unlike MC AVC Sony AVC does not seem to be hard coded to speicifc GPUs and works with newer ones as well. At least it did when I checked years ago when I found out MC AVC was dead with my newer AMD GPU. edit: I am not talking about the Quicksync support in Sony AVC.

Youre right... So...with GPU acceleration disabled, it takes my CPU about 2.2 times longer. (i have a intel 2600k@4,8ghz) But realy, with no CPU in the world can you beat the gtx580's performance. Not even close!. I have tested many CPUs(i7 5960x, 4970k, 4770k, 6700k)... any comparison with a cpu performance is just absurd.

Project settings: resolution 1920x1080, 29.97fps, 8-bit pixel format. source footage - canon 5dmark3 HD ALL-I files. Render settings: MainConceptAVC, Frame size: 1920x1080, 29.97fps,CBR 14Mbps, render using CUDA. 

Basicly rendering 60min of h264 dslr footage in ~30 minutes totaly unachievable for ANY CPU out there.

Mainconcept AVC also has GPU support and it uses GPU support A LOT! and it gives a HUGE boost. In your case is is most likely you dont have a supported graphics card. (just try  the old nvidia 5xx series and se the magic happen). Also SonyAVC is working a little better with newer cards compairing it to MC, but newer cards ar still very very slow in vegas. Also, by default in vegas14, gpu acceleration is DISABLED. - one wil have to enable it from internal-menu.

A simple comparison 1:57 project, R9 380, Sony AVC.....

V13

CPU 1:58 to render, GPU 1:53 to render

V14

CPU 1:52 to render, GPU 1:46 to render
