This will be a quick question before I make it a long one
I just got a new machine with an NVIDIA GeForce RTX 5070 ti. My now retired system has an RTX 4060 in it. Would there be a benefit to add the 4060 and can Vegas Pro be configured to use both?
Thank you
Basically no. Currently you can have IGPU (the GPU on the CPU) and an external GPU configured. You cannot use two external GPU's. At the moment 50 series external GPU's are not yet optimised for V23. I am using a 4080 Super with V23 and earlier versions of Vegas. To do this best to use 581 series Nvidia drivers.
Vegas builds and versions newer than vp21 b208 are optimized for a single graphics processor, be it a gpu or igpu. However, newer versions perform better if decoding and timeline processing all takes place within the same processor, especially if it's an Nvidia with vp23. If you have a 2nd processor from a different maker, like Amd or Intel, rendering with it isn't quite as fast as Nvidia but lets you work around vp23/Nvidia long-gops and vp22 Nvidia driver incompatibilities. I also noticed a slight vp23 performance penalty with 2 x16 pcie boards both dropping down to x8 in most common motherboards. What I stay away from is using 2 pcie boards from the same maker because Vegas always seems to pick the slowest, least capable one for rendering.
Thank you. Howard, what incompatibility are you referring to? I’m currently using vp22 and haven’t noticed any issues
The newest NVIDIA drivers don't allow VP22 and older to use NV Encoding.

@RogerS all good with VP23?
Yes, 23 was built with the newest SDK.
While you cannot use multiple GPUs on the same task in VEGAS, you can use one to do timeline acceleration, and another to do video decoding. Many people do this already by using the decoder built into their AMD or Intel CPUs (QSV, VCE, etc) and then having their primary GPU do the rest. Keep in mind that doing this doesn't automatically give you performance gains, and in some cases it might even hurt performance, so test your own setup in different configurations to see what works best for you.For instance, your iGPU might not be able to decode all the same formats as your primary, or vice versa, or it may decode them slower.
Some plugins also allow you to choose which GPU you use to accelerate them, so you may be able to have a second GPU accelerate just that plugin (like Neat Video), the other GPU handling timeline rendering, and a third doing the decoding. I can't say how much performance gain you'd get from doing it that way, but it is very common for people to use their iGPU for decoding while their primary handles the timeline acceleration.
