Yeah I understand that but I didn't know if memory had any effect on playback. I found this article though http://techgage.com/article/magix-vegas-pro-18-processor-graphics-card-performance/

From what it looks like as of right now Nvidia cards with more memory seem to the better choice for playback, although none of the newest AMD or Nividia cards were tested.

None of the new Nvidia cards work with Vegas. Haven't seen any 6800 reports yet, 3060ti would be good for Vegas from a gpu power level/price as Vegas doen't use much GPU, but doesn't currently work

Nice to know. Maybe they'll be an update before they're actually available to buy.

There's plenty of stock of 3060ti, but if you buy it and put it in your computer instead of an upgrade in performance it either won't work or have degraded slow performance for Vegas. But if you did buy it, and vegas doesn't update to support the cards in reasonable time, you'll be forced to learn new software such as resolve or premiere and that could be the best thing to happen

@lenard
Do you want to help him or just poach him? How much money do you get from Resolve, or Premiere for it?
It's getting embarrassing.

It would be nice if you limited yourself to help again - your specialist knowledge is actually very much appreciated here.👍

@walter-i. I"m in the same situation as the poster. I have missed numerous good deals for 3000 series cards simply because I know I can't use Vegas with it. They've had 3 months to update their software. I do not want to set up a computer just for Vegas. This lack of support for existing users is verging on suicidal for the software

this is an older topic but I know the cpu is the most important for a smooth playback in vegas. But when adding fx a good GPU is also important. Probably i will go for the intel 14700K but i doubt for the GPU.

RTX3070, RTX4070TI or a radeon 7800xt ? Based on this youtube video 7800XT is best and less expensive than RTX4070ti. This was tested in adobe premiere. I mostly use longGOP codecs (4K H264) What are your thoughts so i can finally place an order.

I am happy with my 7800XT. EVERY card has limits, and there are certainly more powerful GPUs. When I looked at price versus performance, I thought 7800XT might be about the sweet spot. I am pleased with my purchase of it.

To playback what? Depending on the media it may be Intel ARC or an iGPU for decoding.

More datapoints on GPU performance in my signature.

For what it is worth, I recently updated to an Nvidia RTX 4060 Ti and have had no problems with Vegas (I'm on version 20 currently).

4k (UHD) sony H264 files. mostly 8bit 50P. So with some effects on it to have smooth playback or in multicam editing with color crading.

UHD Sony X-AVC S 8-bit files is about all that I shoot. I use my Intel iGPU with the 13600K to decode those and it works great. My NVIDIA card handles the timeline (color grading, Fx).

I'd bypass the Fx while in multicam mode as it's really just to make cuts and performance is limited.

@animagic In VP20 I had a problem with Vegas AI effects not using what I think was a rtx4080(may have been 4090), other effects used it, Tried forcing GPU using internal preferences, and reinstalling Vegas (possibly with resetting) did not work. I would have been testing the first VP20 build that used Nvidia GPU for AI. Is it apparent Vegas is using GPU for AI?

Don't expect a big revolution with the gpu change. I am also satisfied with the uhd770 igpu which is part of the intel processor. I have it activated for I/O files h264 and hevc and as the main gpu in the Video folder. Vegas is very stable with this combination. Then it's not a good time to update the Gpu for Vegas.

Wait at least half a year and Vegas will have a new video engine and it will be clear which card is best with it.

problem is now my current pc the preview is laggy without any effects. just UHD 8bit MXF files. I have to drop the preview to preview/auto. And is this case i was shoot in 25P. 2 cam multishoot with my FX6 and Z280. So I have to update for a smooth workflow.

4k Mxf is an unfortunate format for Vegas. A simple effect or transition is enough and the playback is jerky. A better gpu won't help you because mxf is not supported. Try spinning in a different format.

Can you post your file for testing?

Try other formats with your Sony and watch task manager/performance to see what the GPU is doing for playback with each type of file. I wouldn't buy a GPU, just use the one integrated into the 14700K.

If you'd like me to test a file with my UHD770 please post one and I'll report back (Intel 12th-14th generation have basically the same iGPU features for decoding as far as I'm aware).

I have not used the AI, so I don't know at this point. When I have some time I'll try.

To follow up on my previous post, it doesn't seem that the GPU contributes much. When applying Style Transfer, I get almost 100% CPU, while the GPU is taking it easy.

@animagic Vegas does use a lot of CPU and not that much GPU so depending on your CPU that could be normal, this is using a 12core CPU and what I think was a rtx4080. If you set quality to best/auto you should be able to playback in real time or close to real time this AI benchmark, but if it's a huge amount slower it likely is only using CPU.

What I think fixed GPU AI was going to options/preference/video changing GPU to none, restart, and then changing back to GPU, restart. It sounds a little too simple though. GPU AI worked fine from the start with a rtx3080

both cameras shoot only mxf files in UHD. When restarted my computer the playback was a bit smoother. I know I GPU won't help here but a much faster CPU does. I ordered my new build pc with a 14700K intel CPU. I will update this topic when I have it.

now with my new pc (see signature) all my footage plays fine in full best. UHD 8bit H.264 MXF (Z280 and FX6) and MP4 (A7IV)

adding a simple dissolve between MXF clips the dissolve struggles for a real time preview. It's not the case between the MP4 files.
