Freezing when clicking on the top of the video in the timeline

Hello, I recently upgraded from Vegas Pro 19 (Build 651) to Vegas Pro 22 (Build 239) and noticed that if I clicked on anywhere in timeline on Vegas Pro 22, it "freezes" my PC (Youtube video on the side "freezes) for a split second. I tried it without media on the timeline and it did not do that so I thought maybe it was the media but I tried testing it on my Vegas Pro 19 and it was opposite and not "freezing" my PC.

I don't know if its a Vegas setting but I mostly kept Vegas Pro 22 to default settings, only changing the display monitor to my main monitor, while I changed a lot of Vegas Pro 19's settings over the years to not make it crash. If it helps, here is the Mediainfo of the video I tried on both software:

My bet is its going to be OBS settings. This has been a problem many times before. Roger S knows the likely settings to solve this. Limiting the key frame interval to 1 in OBS gives VEGAS easier to edit files. is a previous answer Roger has given.

Hello,

Yes it is already even set to 0.

Try setting it to 1

0 is automatic, 1 is 1 second. Automatic can be 10s or more between keyframes, which VEGAS can struggle with.

Whether this would help with freezing outside of VEGAS I don't know.

Hey Roger,

I recorded using the OBS setting you provided and can confirm it did help with the "freezes" however it is still present when moving clips on the timeline or just even basic use of the software. I read somewhere that Vegas 18-20 are different from 21-22 so I was wondering if I could copy the settings that I have on 19 (file I/O), or Internal settings (CTRL + Shift) or have any tips on how to improve Vegas's performance? Thanks.

No, settings from 19 don't work the same in 22 so I wouldn't attempt that.

You could try a reset of 22 (hold control + shift on startup).

I assume the NVIDIA GPU is on a fairly recent studio driver? There aren't any background apps or monitors potentially conflicting with VEGAS that you could close?

I also assume that the NVIDIA GPU is selected in preferences/video, dynamic ram preview is on 5% or another reasonable value and file io has NVDEC doing the decoding?

Actually I am on the game driver for NVIDIA but I did test out both drivers (DDU twice) and found no difference in performance at all, I then reset Vegas and still the problem occurs. What I found interesting is that when I enable legacy AVC, the performance of Vegas seems to be a bit faster except that clicking down the timeline takes about 3-5 seconds. Also using without it seems to decode the video slower because sometimes the video loses fps when its being played on the timeline. Here are my file i/o settings:
