Caution disabling mitigations. Only enable on air-gap devices (devices without any connection, airplane mode).

MODERATORS
Do you mean I would have to execute the code for enabling and disabling every time I switch Wifi on and off? How severe is this, would it be okay to use it with wifi at home or does that not matter?
Ideally yes, though it would probably also require a reboot to apply. Realistically disabling security mitigations should only expose you to risk when you execute untrusted code (e.g. load a website, run an untrusted program, or etc.), but there's no way of telling if someone could connect to your system using an exploit and then abuse those hardware security flaws.
Consider your own risk tolerance -- is it worth it to you to get that extra few % of performance and risk someone gaining access to information on your Deck (and/or using that information to access other sensitive information)? It might also be worth mentioning that most games aren't 100% trustworthy since we don't exactly know what they're running since game studios don't share their source code.
This is the best summary I could come up with:
A Phoronix reader recently published a guide that at its heart is a set of commands aimed at boosting the performance of SteamOS on the AMD APU powered Steam Deck.
Here are some benchmarks showing the performance impact from these changes on the SteamOS 3.5 Preview release.
The set of changes include setting the Steam Deck's Van Gogh APU to the performance governor, adjusting the MGLRU settings, adjusting the memlock values, setting the I/O scheduler to Kyber, silencing the watchdog timer, and avoiding extra operations on file access times.
See this blog post for all the details and instructions.
Following my recent SteamOS 3.4 vs. SteamOS 3.5 Preview benchmarks, I repeated the SteamOS 3.5 Preview run while applying these optimizations as recommended.
No other changes were made to the Steam Deck besides making the noted changes and then repeating the benchmarks.
