GPU Acceleration Nvidia RTX 2080ti

Hello everyone,

I have 2 PCs with Vegas Pro 15 installed (one for editing one for rendering) and all my files are on a server in the network. So both PCs uses the exact same files.

PC1:
Windows 10
i7-6700K
Nividia RTX 2080ti (driver 418.91)

PC2:
Windows 10
i7-6700

So the main difference is that PC2 only uses the Intel onboard graphics card.

The problem is that I cannot activate GPU acceleration in the preferences for PC1.
I thought that option would only impact performance and how effects are calculated in the preview… Didn’t thought it would mess up the whole project. I noticed that my watermark on PC1 is very pixelated. Also shadows on the texts are missing.

e.g.:
Watermark on PC1 (just a .png image with transparent background which is downscaled in Vegas):

PC2:

The picture was taken from the preview (snapshot with terrible jpg compression) but rendering (regardless of which option) doesn’t change it.

I double checked all options on both PCs and narrowed it down to the “GPU acceleration” setting under preferences.
On PC1 it is off and I can’t choose the graphic card and PC2 has the onboard graphic card activated. When I turn this setting to off on PC2 I also get that pixelated image.
So in my opinion something with the scaler is off when GPU acceleration is turned off.

Things I already tried:
Installed the trial of Pro 16 with the same result. (pixelated image and no GPU acceleration available)
Reinstalling drivers didn’t help.
Allow legay GPU rendering did nothing.
Setting vegas150.exe in the graphic options to high performance didn’t help.
Installing Cuda Toolkit didn’t help.

Is there any other workaround how I could get a correct image?
Can anybody confirm a normal behaviour of Vegas and a new Nvidia RTX graphic card?

I found a workaround to the problem.
I activated the iGPU from the Intel CPU in the UEFI BIOS and now I can choose the Intel GPU under GPU acceleration and get a correct image, no pixelated layers or missing effects.
Would still be nice to use the power of the 2080ti not only for the encoding process later in the workflow…

I hope someone will find this helpful!

On my desktop from signature I had to activate both Intel and Nvidia in the BIOS, followed by connecting my main monitor to the motherboard and my 2nd and 3th monitor to the NVidia. All settings in Hardware acceleration and renderoptions for NVidia and the Intel are present as I showed here many times.
