So much CPU and RAM usage!

I used Brave for some years since it was the lightest browser to use in my PC. However in december of 2022 i switched to opera GX due to CPU and RAM usage problem.
Since december Brave use too much resources for too little. for example, right now, with only the tab for this post open, it’s using 55% of my CPU and 2.6 GB of my RAM, while on opera GX i have my e-mail and other 18 tabs open and it’s using only 1% of my CPU and 1.4 GB of my RAM.
If i have the option, i prefer to use Brave browser, but in this state it’s impossible for me. I’m currently using Brave 1.49.120
