As i have 64 GB of ram I think I can disable swap or give it problems with some apps? Like on windows?
Is zram needed or is it better to remove bec as I read it's only compressed swap. So my thinking was that the performance should be better without swap and zram or I am wrong?
Yes
First world problem
To be or not to be, its regardless
Only my personal opinion.
True :).. Thx . But its only for interesting bec I like to understand and use it the best way
You are unlikely to hit swap under any normal circumstances, but that doesn't mean that there may not be advantages to having it enabled. Here's a link to an explanation of why this so, if you're interested.

Personally I haven't had a 'swap hit' in years (currently on 32Gb) but I define it anyway
With 64 GB of RAM, you don't really need a true swap partition, but you can use zram without a problem.
I do hit swap sometimes on 32G, but it's only zram as well.
Zram though is not simply a compressed swap.
It's handled like a block device and you can format it with most filesystems and put anything in it, including swap.
zramctl
shows current status.
