Video FX not previewing effect

I have Vegas Pro 13 and usually when I drag the effect to my video before I exit it would put the effect on the video so I can look at it but I dont know what happened and now after I hit the X is when the effect is on the preview. I attached a video

Similar problems have been reported a few times. It's to do with your graphics card driver. These threads may help:

i'm having this same problem too, i tried following the links provided but they did not give me a solution to fixing it. can someone please help me?

UPDATE:

here's the solution that helped me, it was posted by

michael-harrison in this thread: https://www.vegascreativesoftware.info/us/forum/problem-with-384-notebook-drivers-from-nvidia--107455/

Open the nvidia control panel (rt-click on desktop) and under Manage 3D Settings | Program Settings find Movie Studio in the list or add it if it's not there. Choose "Integrated Graphics" in the preferred graphics processor dropdown. Save.

Open MS and choose the Nvidia GPU in the Video tab in preferences.

Now you should see that the titles/fx/etc update in real time.

But also...

When you render, it will use the nvidia gpu. You can verify this by opening the Task manager and watching the GPU Engine column (enable it if it's not there) and you'll see GPU 1 show up when you render.

Unfortunately several comments in those threads were deleted, so they are no longer so helpful. Thanks for posting what worked for you.

The updated fix for this is to reset the NVIDA Control Panel settings to the defaults. Then in Graphics Settings (type it into the Windows 10 search box) change Vegas to "High Performance." Since an April hotfix, Windows has had the capability to directly control the Gpu used per program. Within Vegas set the GPU to your NVIDIA card.

For me this gets rid of the preview issue with a GeForce1050/Intel Integrated laptop. I still have graphical glitches when rendering if there are picture layers above video layers and have to render with GPU acceleration off.

@RogerS So is part 2 of the FAQ post about this now out of date? Do you mean Windows now has the capability to directly control which GPU is used by each app?

RogerS wrote on 9/8/2018, 11:01 AM

Yes to your second question. "Graphics Settings" does just that.

I never really got the previous advice to work so I can't say if it is no longer relevant to anyone. There are at least 3 people here who are benefiting from this new fix though.

I am using a laptop with current Nvidia drivers on a system with switchable graphics. Vegas 15 387 and Win 10.

Yes, that's exactly it.

Magix support told me that this update caused GPU issues and tried to have me roll it back. I was unable to do so and still have render problems, but at least the preview issue seems to be solved.
