I just noticed. I spent a lot of money on equipment that Vegas can't use. Time to switch to davinci :(
Something doesn't line up here...
Good luck switching to Resolve with that graphics card, which began life over 10 years ago, and doesn't meet the min specs for either Vegas or Resolve. Buying a 13th gen Intel, 64GB of RAM and using that card? And you have Vegas 20, which hasn't been sold since the release of VP21 in the late summer last year? And this is your first post about problems? And there is no suffix designation of what Intel CPU is being used.
To me, I agree with @Adis-a, something doesn't line up here.
I have an Asus Strix 3080 ti 12gb for testing. Vegas works much better, but it is clear that it cannot use the full power of the hardware.
How would you know? What is the "full power" of the hardware?

@Reyfox The limiting factor here is the GPU decoder, With 6 tracks of 4K50 10bit the decoder runs at 97%, and it takes a few seconds to stabilize, so the weak point should be the single NVDEC used in consumer Nvidia GPU's that's maxing out around 300fps at 4K10bit, a maximum 6-cam multicam to not drop frames. The problem is Vegas can only deliver 5fps when playing these 2 tracks concurrently. His 3080ti test GPU has more than enough processing power for this test and the same GPU decoder as my card.
The new Decoder is not working as it should and neither the full power of the CPU or GPU can be harnessed for Vegas processing. This is something I established in the first week of VP21 release. It hasn't been fixed yet.
If you're wondering why the frames don't lag the moment the 2 tracks play together it's because the new decoder uses a VRAM cache to help with smooth playback, when the cache runs out you get the real performance
I just bought a brand new computer myself and thought the same thing - "I spent a lot of money on equipment that Vegas can't use."
Here are the things changes that I made that really helped me "...have a smooth preview."
1. Hardware Decoding: Options > Preferences > File I/O > Hardware Decoder to Use - Make sure this is set to the correct brand. By default, myne was set to "Intel QSV", but i changed it to NVIDIA NVDEC as I have an NVIDIA graphics card.
2. Preview Quality: I have myne set to "Good Half" or "Preview Half". Not Full, it struggles. If it still does struggle, try right click preview screen, and select "Adjust Size and Quality for Optimal Playback", and it will Automatically adjust Preview Quality to maintain your frame rate.
3. Create Video Proxy: If preview still looks crap, (and it usually does when i have video over video), then Create a Video Proxy; Project Media tab > Right Click Source Media > "Create Video Proxy". It switches your full-quality source media for lower-quality proxy media while you edit, then switches back to the full-quality files automatically for rendering. The lower quality proxy media even allows me to view Preview Quality at "Good Full", looks clear and maintains framerate no problem. You may especially need this when working with 4k. You can even set it to Automatially Create Video Proxy for 4k video in the settings; Options > Preferences > Video > "Automatically create video proxies for greater than 4k resolution media"
Those 3 things actually allow me to use my computer, otherwise I'd need to send it back, or it was useless. Good luck, i hope you can get yourself a smooth preview.

Intel QSV is generally the better choice in VEGAS. It supports more file types and is more stable (especially with HEVC). Just because it's integrated on the processor doesn't mean that it's worse than your RTX card. For encoding and decoding it's comparable.

Maybe thats true if one has an Intel graphics card, but not if one has an NVIDIA graphics card, or say an AMD graphics card. How do i know? I can easily set myne to Intel QSV and watch my preview framerate drop through the floor.
@Cam I don't know why that is, especially with Vegas is assigning the decoding to your Intel IGP via (auto) option, for your given files it may not be better but generally the expectation is that it should not be worse. What is your CPU, and what are the file specs for a piece of media that behaves that way?
Also keep in mind none of what you said can help the OP or myself with 4K5010bit HEVC Multicam editing , the Vegas decoder is faulty. It's always important to acknowledge a fault where one exists for a customer to save him time and money attempting to fix something or buy a new computer. Your proxy suggestion can hide the problem though, but I am guessing it shows up again in slow rendering, although haven't tried. Your proxy advice is slightly off, Proxy only works on display setting PREVIEW, when you switch display to GOOD, it's decoding original video, or this is my understanding. I don't use proxies.

My CPU is 13th Gen Intel® Core™ i9-13950HX processor, my GPU is NVIDIA® GeForce RTX™ 4070 Laptop GPU. The step 1 I mentioned was the step that gave me the most improvement.
Using a proxy was a last resort for me if the first 2 changes were insufficient. As none of the other suggestions i had found... https://www.vegascreativesoftware.info/us/forum/faq-how-can-i-make-my-video-preview-play-smoothly-in-vegas-pro--104624/
...really helped me much.
"Your proxy advice is slightly off, Proxy only works on display setting PREVIEW, when you switch display to GOOD, it's decoding original video, or this is my understanding." This is 100% correct, and wrong on my part. What I should have said is PREVIEW FULL. Thank you for correcting me. These issues are making the DaVinci Resolve alternative a more enticing option every day.
@Cam Assuming you're talking about the same Hevc media this thread is about, consider checking off the Experimental-Hevc box when selecting the Intel igpu for decoding. That will lower decoding quality to the level of Nvidia while making Intel decoding faster. As demonstrated in 3rd group of the chart in this thread:
Btw, that lower level of Nvidia decoding quality with Vegas is also the best Resolve gets no matter what you do or use.
I changed vegas to davinci. I recommend to everyone. Great working comfort. 0 stability issues. The program works quickly and efficiently. I can take a live view from up to 6 devices. I thank Vegas for 15 years. Time for change. Vegas is a nightmare in 4K. I recommend to everyone. Don't waste your time fighting Vegas.
@Lukasz-Pecak If you're using formats that can take advantage of Intel QSV decoding in Resolve Studio it may help you further. Here's a useful list: https://www.pugetsystems.com/labs/articles/what-h-264-and-h-265-hardware-decoding-is-supported-in-davinci-resolve-studio-2122/
@Lukasz-Pecak enjoy your learning curve. I have Resolve Studio, so know what I am referring to. As for Vegas and 4K, I edit almost exclusively 4K footage.
Use what works for you.
Just got the body and lens for my 3rd 4k camera which will also be shooting hevc in my multicams. Up till now I rarely used proxies and only when using a 4:2:2 hd xf305 camera in the mix when all 5 cameras had to be shown at once in pips to select where to cut from one camera to another. Here's my 1-day old c70 which will retire the aging xf305:
As for the Vegas vrs Resolve debate... I've verified that Resolve Studio loads c70 cRaw CRM clips which Vegas cannot. However, Resolve's quality limit is so much lower than Vegas' Hevc, making cRaw a non-starter for me.
