I just got a new system and upgraded from my old system. However, I am having extremely high render times. Near 110ms at times. I upgraded because I was getting render times of 35ms before. My new system has Windows 10 before I have only ran Windows 7 with vmix. I went from a GTX 750 to now a GTX 970. What could I be missing or what setting could be wrong. There is no reason my new system should be 110ms for rendering. Is there anything special I need to know about Windows 10 or is there some reason its may not using the GTX card I made sure it was selected under the setting section. This is very frustrating but I know it has to be a setting or something. It makes my video looks very choppy.

Hi,

Download the GPU-Z utility and run it to make sure everything with the new graphics card is ok.

Looks like a big fault somewhere, possibly one of the following:

1. PCIE Power cable not plugged in to the 970 correctly. The 750 by comparison either will use a different power cable or none at all.
2. Check the slot the card is installed in is the full sized x16 slot closest to the CPU.

If the slot isn't working correctly you will see under Bus Interface in GPU-Z something like PCI-E 3.0 x16 @ x4 or x1
(x8 or x16 is normal)

After looking at that program further... this is prob the screen shot you would want. The performance. I am also having an issue of video that are loaded not playing. When I advance to them its just a black screen. If I reload them they work fine. I am really wondering if this is a Windows 10 problem. I have never had any issues like this. And my GTX970 card doesn't look like it is working fine.

In my opinion the best what you can do to reinstall the system with win8.1. For me - solved all my problems.

So I changed the recording encoding to 264high and I have low latency on... my render times are now dropping to 6-35ms. Does that recording encoding effect the streaming. I do record my streams... but the live streaming is where I was running into issues. That doesnt really make sense but it has seemed to help.

Does anyone know what is normal to use the Hardware encoder or not too? I am still having issues and trying to figure this out. I think I just have my vmix settings all out of sync. This is stuff I have normally never adjusted.

Hardware encoding will make your H.264 encoding process be done by your graphic card (GPU) and not by your CPU. It's a good idea to use it if your graphic card supports it as it can reduce the load on your CPU.
