Hello all,

After a couple (a lot) of testes, I decide to clear all configuration and start a new fresh setup.

My experience:
OBS 19.0.2
Windows Server 2012 R2 "Azure - Basic A2 (2 cores, 3.5 GB memory)"

Close OBS
Open and clear all content in C:\Users\YOURUSER\AppData\Roaming\obs-studio folder.

Open OBS
- A Popup appear asking me to run an Auto Configuration Wizard ( at this point my CPU point to 93.4% Usage, just for OBS64.exe)

- Wizard steps:

After all wizard thing I got , incredible +90% in CPU :(

It was very sad because, I am not streaming yet :( .. at this point some people will think.. WTF? Are you trying OBS in a Virtual Cloud Machine? Why not use my own PC right? I can explain :) My idea is create a online radio on Youtube :)

so... after some research I saw a lot of guys talking about High CPU usage in last OBS update, but it was a little bit frustrating because I am not streaming yet ... I just open the software and get +90%...

So if it is not a streaming issue what is this?

Back to OBS Options and selecting "Video" tab, I found this BASE Resoltion 1366x768 and OUTPUT Resolution 607x341. Here, my first test was change Base Resolution to 1920x1080 and apply, NOT Happen :( , so I tried 1280x720 and apply, NOT Happen again :( ... more research and I found a page with Youtube Resolutions. I choose now 854x480 and apply, NOT Happen... push it more... 640x360 and apply.. at this point CPU down.. -70%

and.. drop even more after set Downscale to Bilinear and FPS to 24 ...

At this point I figured out that Video Settings, have a direct impact in CPU usage, even you are not streaming ..if I am not wrong "Output (Scaled) Resolution" precisely..

I think 640x360 is equivalent to 360p , wich is good for me for now ....

So ... If you is having issues with CPU High Usage .. try to check you Video settings...

Thanks.. Learning and Sharing...
BTW: Sorry my English...
