To begin, these are the components of my PC:

Operating System: Windows 7 Ultimate 64-bit

Processor: Intel Core I5 ​​6400 Skylake

RAM memory: 16GB

Video Card: Gigabyte GeForce GTX1050ti G1 Gaming 4gb ddr5

Note: Before installing Vegas Pro 15 I made sure to update all the drivers of my video card.

The issue is that the software takes a long time to render my videos. For example, in general my videos last 10 minutes, I render them in a resolution of 1920x1080p at 60fps before I used the templates of "MainConcept" and finally those of "Sony AVC / MVC" (the videos usually weigh 1.5Gb but I do not care about the weight but the rendering time). The last times have taken up to 6 hours to finish and I have even been wrong when the process exceeds 60%.

My projects usually have 6 tracks or more: two tracks are from a gameplay (from a mobile device game) and its soundtrack, another track with the background music and SFX, three tracks that have images in ".png" format above the vieos (PIP) with slight movements (watermark, frames, etc. There are approximately 60 images that change every 10 seconds). I almost did not use any visual effects, just track movements and "event panning / clipping".

It is even necessary to edit with the preview in the "Draft / Total" quality so that it looks fluid, in another quality it loses fluency.

To further complicate my uncertainty of what is causing this (I enclose an image that summarizes what I emulate below), I have tried to take advantage of my GPU (which has CUDA technology). But, although in the preferences of preview, in the tab "Video" it says: Acceleration GPU of processing of -> "Here it appears my graphic card", when I click in "renderizar like" and I edit one of the templates selecting "Render using GPU if available "and then I select the" System "tab and click" Check GPU ", I get a text that says" No GPU available ". I also had to activate the option "Allow legacy GPU rendering" in the preferences of the preview, in the "General" tab.

Until a few months ago I used "Vegas Pro 13" and I think it took a lot less, or at least it allowed me the option to render using CUDA.

I was also looking at the MAGIX rendering templates but I did not see any that used the GPU, or at least I did not find how to configure them.

I would like to take advantage of all my PC to edit and render, what could be causing all this? Could it be all the images that I put (which occupy only 5% of the screen)? Not to mention what it takes when I add effects, or projects within another project.

You tell me test I can do to rule out options and get to the problem, I give them back what they need to help me.

Thank you all.
