I updated to AMDs GPU Driver 24.6.1 on the 8th through AMDs Adrenaline software. I had the same issues with the previous drivers as well.

I use proxies tho i turn the auto proxy off just because i like to allign my footage and cameras and use AudioR from happy otter to align my clips between cameras and save it before making proxies cause they take so long to make.

And yeah this gpu blew my mind when i tested it on BF2042. Was hoping the same for vegas. (the sole reason i bought the card in the first place.)

If it was working but is no longer (with the same media, same Fx, etc.) have you tried a reset and cache clear of VEGAS? Sometimes it can help.

Yeah that has solved it in the past, but this time i did it numerous times and nothing sadly. Ive reinstalled vegas who knows how many times then went back to build 300 then 208 then back to 300 then back to 315 and no difference unfortunately.

Preciate the suggestions 👍

Just for testing purposes I'd stay on 208 as it's a known good build.

If you can try the VP 20 benchmark and fill out the results we can see if it's performing poorly across the board or just with the media and Fx you are using.

Dynamic ram preview at 0 will kill performance- try it at the default of 5% and see if it helps.

Your other settings look normal.

Alright ill try that when i get home from work

IMHO
You can try to install the program XviD4PSP (latest 8.1.84). There is a hardware speed coding test. At least it will be clearer if it is a system or a specific program.
For example, for my system:

Okay cool ill look into that. Got some stuff to do later. Preciate this guys.

Put this to the side for a bit to email support. Not sure how I feel about it, but I'm back.

Here are my results.

I have now officially purchased and installed a fresh brand new copy of windows 11 pro on a entirely different drive. I tested this drive with whatever the programs called and it read at 7062MB/s and wrote at the same speed. I did all the drivers and updates necessary for a fresh install of windows. And still have the same problem. This time i opened task manager and set it to refresh as often as it can and it shows Vegas uses 100% gpu and ~42% cpu for 1 second, then 0% for both for about 5-6 seconds cause its frozen and i cant click anything in vegas and windows pops up saying, “Do you want to close this program or wait?” then 1 second then 5-6 seconds, on and on. This makes for horrifically slow renders when if it still rendered like it did before, it would be burning through this clip in seconds.
 

I'm officially convinced this is a Vegas issue. More specifically a rendering issue.

i installed capcut on this system when i had windows 10 still and it performed as expected. 🤦‍♂️

What setting in vegas do i need to change or is the update for the 7900 gpus flawed Majorly? I don't understand.

Are you on build 208 or 315?

Did the VP 20 benchmark in my signature have the same issue or is it project specific?

There's no particular setting you can change though you could try the legacy decoders in preferences/ file io if it's a decoding issue.

@FOVAirsoft the only one that I know of that has a GPU close to yours, but a previous gen is @Howard-Vigorita.

As you saw in my screenshots, the GPU is being used and I have no issues

That was the other test i was supposed to do. Sorry let me do this right now. Just woke up. Also im back on 315 now. I completely wiped Vegas (delete all app data, documents folder, etc) from my pc and reinstalled, 300, then 208, then 300, then 315. Did the same render issues each time.

So here are the reults of the Vegas 20 benchmark,

Mainconcept Rendering Behavior:

Mainconcept Rendering Results:

AMD VCE Rendering Behavior:

24% render completion AMD VCE:

40% render completion AMD VCE:

AMD VCE Rendering Results:

Remember this is a fresh install of Windows 11 Pro, All drivers and updates updated, Fresh install of vegas 315. and its still performing the same way. renders for split second, freeze for 9 seconds (timed it this time) then renders for split second, etc.

Vegas has no issues using up to 100% GPU load (avg 65%) and 60% CPU load (avg 30%) during playback at Best(Full) but once it begins to render it refuses and freezes up and performance all falls apart. Makes no sense to me.

Any other system tests I can try? Gonna download 3DMark and compare the scores to when i first got the 7900XT and see if anything happened to it.

Could this have anything to do with my issues?

Very odd. I don't have an AMD system but looking at the VP 20 benchmark results (go to data/ change view and then AMD GPU) I see only one other user with a 79XX system with VP 20. Total time was 3 min (7 min when he disabled dynamic ram preview).

So you at 40 min are way off the mark and are underperforming laptops from 2017.

The first thing I would do is set dynamic ram review back to 5%. Keep preferences/ file IO at defaults. Do not change any other defaults in VEGAS so we can get a proper baseline.

If that still results in an extremely slow time try build 208 again which is the last of the builds in the 20.411 line before big video engine changes. There's a possibility the new engine and this GPU line doesn't work well- I don't know as there isn't data.

Ill have to try it again one of these days, unfortunately I've got 4 days to edit together a video that usually takes twice that time while also dedicating apparently like 15 hours to the render itself.

Here are the 3DMark scores i referenced earlier. Safe to say its not my system.

#3 is when i first installed my 7900xt. (Stock Settings) Smooth Vegas renders.
#2 Is when i overclocked the GPU to the absolute limit. Smooth Vegas renders.
#1 was just now, (sock settings) and did better than when i first got it. Horrific Vegas renders.

I just want to say everyone replying with suggestions is far more helpful than the support team. I've been ignored multiple times for days on end and have to reply again asking for a response to get one. Best I've heard yet was go to your last restore point, did one better, installed a new windows on a different drive. Same problem. Feel really great spending ~$370 a year right about now.

Wow you get 100% gpu usage? Ive never gotten that before. Id FLY through renders if i did lol i don’t know, I’ve checked every setting i can think of for the last 3 days straight. Drivers, Virus scanning, windows SFC /scannow, Tron, i swear I’ve done it all.
Cant figure it out sadly.

• Add VEGAS in exception list in your antivirus (sometime real time scanning cause problem)
• Ask someone for preferences export file then import those preferences then run your project again.
• Try Following setting if you don't try

• Try following methods

• Try this AMD driver version.

i am not sure it will work but u can try.

Good luck with your project and when you get a chance let us know if any of these tips help.

Is there any kind of GPU monitoring software in use? I forget which one it was but read about conflicts at some point. I'd try to disable/ kill in task manager any other software that is running when you do the VEGAS benchmark and see if that helps bring you back to the good old days of renders you had.

@FOVAirsoft here is a link to download AMD Drivers direct from AMD older than the current 24.6.1.

Did you build your PC? What if you change the PCIe slot where the GPU is located? Yeah... I know a pain. But if you get a different result from the other PCIe slot, it could point to bad motherboard. Or, if you know someone who can put your card in their PC to test, that is another way to confirm if it's the card or motherboard.

Something is definitely wrong with your PC.

Im pretty convinced at this point that It’s not the system itself. It’s specifically the Vegas render process. Every other program, games, benchmark software, etc run flawless. The 3Dmark scores are a good representation of this. If something was wrong with the system itself my score last night would not have been better than when I first installed my GPU. Also keep in mind, vegas runs flawless until i render. Once it begins to render, thats when it takes a 💩.

If you have suggestions on software to test the system and prove thats not the problem, I'm all ears. The 3DMark scores were from FireStrike Ultra 4K. That benchmark tests CPU, GPU, then both.

Also, last night i went back to build 314, 187, and 108 because i haven't tried these yet, and no dice. I also rolled back my AMD drivers and tested every 2.4x.x they have released, and no dice.

I did notice build 108 didn't want to use my GPU for playback in the timeline and it was using like 80% cpu every other one after it uses a fair amount of both CPU and GPU for the timeline and it runs smooth.

What I don't get is why it used to work but doesn't any longer- there must be something that changed.

Build 314 is basically 315 with bugs- I'd skip it. 108/187 are fine but 208 is like a finished version of these builds.

I think Firestrike has a clue:

It should *not* be unknown GPU, it should have your model. Was there a GPU bios change along the way? Was there a switch from an OEM driver to generic AMD driver or some other change?

When i installed 3DMark through steam it installed the wrong “SystemInfo” version. I went to the website and downloaded the latest 5.7.x version and then the program booted right up without error though i don’t understand how it didn’t detect the hardware seeing as it says it cannot upload the results if it cannot verify the hardware. But it did. Lol yeah idk what happened there tbh. Apparently Im not the only one that experienced this issue and I've had times in the past where 3DMark refused to even open on past builds.
