TLDR: Which distro is better for gaming and video editing (NVIDIA GPU), CachyOS or Ubuntu?

Hi! It's been probably a month since I started using Linux (escaping from Windows), and I choose LMDE since the distro that I felt aligned more with what I want from a distro on in general is Debian, but since it was my first time using Linux on my main device (just tried Debian on a laptop to run a Homelab) I got recommended Mint to make it easier for me to adapt. The thing is that since I started using LMDE I've discovered that it doesn't cover perfectly my needs. Two things that I didn't want to lose when switching to Linux were gaming and the ability to run video/audio/photo editing programs flawlessly, mainly DaVinci Resolve and AffinityPhoto. It's been practically impossible to achieve that, since DaVinci doesn't work, can't even get to install AffinityPhoto and some videogames need more recent (NVIDIA) drivers than what Debian and of course LMDE can offer. So, seeing that I want to keep LMDE (and maybe in the future upgrade from LMDE to Debian) but at the same time I'm not willing to give up on those 2 things, I believe the dual-boot option is the one that suits me the most. Now, what I'm here for. I've been doing some research and the ones that caught my atention the most were CachyOS and Ubuntu:

• CachyOS: PROS: · High gaming performance and (looks like) compatibility. · Looks like DaVinci works perfectly for a lot of people (although some other people claim having issues). CONS: · Sounds too complex as a distro for someone who has close to zero programming knowledge and just started using Linux. · The rolling release aspect feels a little scary too.

• Ubuntu: PROS: · May not be THE gaming distro but it seems to be working for a lot of people without having extensive programming or Linux knowledge. · Generally may be more compatible and stable than CachyOS in general · Seems it will be easier for me to adapt to since it's Debian-based. CONS: · Doesn't seem as good as CachyOS on a performance standpoint, affecting both video editing and gaming capabilities.

Now, my questions would be: Am I mistaken in any of the info I have revolving these two distros? Could I be missing any other options? Which do you think is the distro that could suit me the most? Any recommendation when doing the Dual-boot? I have never done it and it scares me a little tbh.

My main priority is having a stable (and compatible in the first place, of course) experience (maybe Ubuntu?), but I don't mind having to put more work into it to achieve a better experience (maybe CachyOS?).

I would love to hear from you and, of course, if I'm missing any relevant information I'll be more than happy to share it too.

Thank you very much! :D

For context: I have 0 programming, coding, etc. related knowledge.

For some months I've been dedicating time into setting up a Homelab that hosts music, movies, maybe home security (Frigate, I suppose), minecraft servers (or maybe other games too) and maaaaybe local AIs (if I get a better system), in that order, from more to less important. Some of the caractheristics that I prioritize are: privacy first, Zero third-party exposure, disk data encryption, self-hosting, FOSS priority perspective, trying not to compromise in any way my home network-using devices through all the process. Since, as I said, I have 0 programing or even Linux experience, I've done all this process guided by a local ran AI (Qwen 3.6), YouTube videos and forums (not the perfect formula for a cybersecurity safe environment, I know).

In an old laptop (Acer Aspire ES15-... with AMD A6-6310 / 16GB RAM) I've installed Linux Debian Trixie 13 (GNOME) with Docker and CasaOS with Jellyfin (for movies, it worked), Navidrome (for music, also worked) and recently Netbird, this one to connect into the local network from outside my home net, which kinda worked, but not as I expected it to work.

And this is where I feel I'm stuck. My main absolute priority the whole time setting this all up was being able to stream music from my homelab in my phone from everywhere in the world as long as I had internet connection, but when I managed to achieve that connection after soooo many hours and even stream music from my phone only with mobile data, it needed like 1 minute to load 3 seconds of a song, so it's not enough at all. After seeing this, I've reseted all netbird data so I can do a clean install.

I need help with the process of setting this (I believe it's a VPN) up in a way that it is Self-hosted, secure and fast enough so I can make it all achieve my expectations. Any video, forum thread or personal recomendation that you can give me will be so much appreciated.

Summarizing it a little, this is what I was trying to achieve:

CasaOS Architecture: Netbird (FOSS WireGuard mesh) + (maybe) Caddy Reverse Proxy + (maybe) Internal PKI + (maybe) LUKS Encryption Security Model: Zero port forwarding, outbound-only private tunnels, device-by-device approval, end-to-end HTTPS, full data-at-rest encryption.

Let me know if I'm missing any important information and I will do my best to share it.

Thank you so so much in advance!!
