@Diego_C. If you're wanting more speed it doesn't sound like the 16GB is any faster than the 8GB, more memory doesn't increase speed - 'The Nvidia RTX 4060 Ti 16GB doubles down on VRAM but has the same underlying specs as its 8GB sibling'

The 16GB version is more future proof, especially if you intend to work with other apps like Resolve. For Vegas Pro 22 8 GB will be enough today.

I’m going to buy a RTX 4060 Ti for my new pc (i7-14700kf with 32 gb ddr5-7200 ram).
There are two versions of this card, one with 8gb ram, the other with 16gb.
Does the 16 make a big difference general functioning of Vegs and in rendering speed?

I use the 16 GB version. Since I am writing shaders, among other things, I need more memory, and this is justified. If you are doing "heavy" projects in Vegas and beyond, especially those loaded with shaders, your choice is 16 gigabytes.

Working with Vegas and using the AMD RX 6700XT which has 12GB of VRAM, depending on what I am doing and what effects are being used, I've had the VRAM usage over 11GB. And I am sure that an 8GB card will work, I would have to start wondering how much system RAM or hard drive is being used as virtual RAM, which does slow things down.

I even wonder what VRAM usage I would see if I had more that 12GB.

@Gid, when working on your projects, how much VRAM is being used?

The more resolution you use, the more effects, etc, the more VRAM you will use.

@Reyfox Hi, it varies but quite often it's in the upper 3rd.

Playing this UHD file + a png it was as in the picture, I added BCC Atmospheric glow & it didn't go up by much.

UHD clip with Boris PI, RAM can reach huge amounts, I don't notice any 'lag', I bought a PC with that amount for my software to use it. both can stay like that tho (not always), only closing VP clears it, I don't know what that is all about.

@Gid thanks for the screenshots. Now I wonder that if I am using most of my VRAM, does system RAM get used to continue editing.

I will be monitoring things going forward. Thanks!

I think the question is inaccurate.

In the last screenshot @Gid for example (red circle) a shader engine is used, it counts each point of each frame, accordingly occupying memory. Incorrect shaders can simply clog GPU memory, while there will be a lot of RAM. The question is much more complicated, it's a simplification.

Often people throw a bunch of unnecessary shaders, clogging up the video card - the video slows down. They complain about the editor. He has nothing to do with it, the video card does not have time to give frames.

From personal experience my first advice would be not to buy the i7-14700kf version go with i7-14700k the IGPU on i7-14700k will really help you decode some of the high end codecs that's used in cameras now a days like HEVC 10 bit 422 even the RTX 4090 couldn't decode that. so going with i7-14700k is like future proofing your self and it also decodes every other codec the RTX 4090 and any other RTX 40 series GPU can.

As for the GPU since the newer version of Vegas Pro 21 Build 300 and onwards continuing to Vegas Pro 22 because it uses the newer video engine it really uses allot of Ram if you select the IGPU as hardware decoder and allot of VRAM if you use RTX 4060 ti 16GB. if you add video fx and luts Vegas Pro will use as much as it can so the more the better. But as RogerS said above quote (if the RTX 4060ti 16GB ram model were the same price as a higher end model like the 4070 I'd get the 4070).

Agree with @Abubakar. Only thing I'd add is to also consider the latest 7000-series Amd gpus and ignore gaming performance unless that's more important to you than Vegas. Fwiw, I don't do gaming but get better overall performance from a 16gb Amd 6900xt than from a 24gb Nvidia 4090 with Vegas past and current versions. And my Amd gpu isn't even the latest.

Yes AMD is also a very good option Lots of Vram and power for a lower price. AMD only has some issues regarding its drivers in Vegas Effects but i don't think Vegas Pro 22 would have any issues with it.
