[Solved] Huge FPS hit with 7.5.8, can you help me pinpoint the problem?

[osd_daedalus]

Hello!
I'm not sure if what I am reporting is a problem with OXCE, XCom-Files or my configuration... so I'll post here anyway:

When I was using OXCE 6.8.4 all was working like a champ. Now that I'm using OXCE 7.5.8, I am experiencing lots of FPS loss especially in battlescape, which looks like to be Z-level and resource dependant. While in vanilla OXCE this is somewhat negligible, in XCF many parts are almost unplayable (i.e.

Spoiler:

the alien moon satellite map

, dropping up to 2-3FPS when camera is on the turret and the wall). I remember not to have problems like this before with areas with many Z levels like

Spoiler:

the Syndicate tower

etc...

My specs are: Intel i5 11400F, Nvidia GTX 970 (yea, that's due to crazy RTX prices ), 16GB DDR4 RAM . Running Kubuntu 21.04

What I have done so far:
- of course, updated OXCE and XCF. To be honest, I cloned again the repo as I did some mishaps before
- updated Kubuntu from 20.04 to 21.10
- updated NVidia drivers to 510
- removed the .config/openxcom folder in home and let OXCE recreate them
- turned on and off VSync, Lazy loading, tried filters...

On a side note, getting tons of segfaults on loading XCF or quitting OXCE when XCF is loaded. Looks like is something with fluidsynth or anyway audio-related...
This is the log in the latter case:

Aaaaandd... as always, after hitting my head very hard for 3 days, just as I post on forum I found the solution!

It's... I used to run cmake ..
I had to run cmake .. -DCMAKE_BUILD_TYPE=Release -DDEV_BUILD=OFF -DBUILD_PACKAGE=OFF

Much likely I was going so slow because I was playing a debug build...

Moral: always read at the sticky post!

BTW: the instructions on Linux compiling, as per https://openxcom.org/forum/index.php/topic,7048.msg111476.html#msg111476 ,  are somewhat outdated.
You don't need in Kubuntu 21.10 to compile separately yaml-cpp... if you do that you are going to get a lot of errors at the end of the source building.
Moreover, looks like there is no more need to create a build folder, it seems all is build in the bin folder.
