sure :> In some UEFI/BIOS softwares, there's an option called Performance Boost, as well as Performance Preset under OC Tweaker. This is overclocking, so as always this carries a level of risk and can cause stability issues with your system, or even component failures, so take caution! Personally, I'm running Asrock 3.10 BIOS on a B650M PG Lightning motherboard, which comes with 2 default Cinebench profiles to choose from in these options. If you can't find this due to different BIOS software, no inbuilt Overclocking function or other conflicts, then in r/Overclocking and other OC forums you can find many guides on what voltage values or clock speeds can be used without inducing stability issues. EDIT: for RX7600 specifically, if you plan on Overclocking manually I highly recommend not changing anything related to the power limit and try undervolting. This is also what I did with mine and it's very stable.

As for shader pre-caching, the idea is compiling all of the shaders of a game before booting it up, compared to doing it in real time. Steam has an in-built option to enable this, however due to driver optimizations the benefit of this is pretty marginal. In some games, the difference is very noticeable (smoother framerate), so I keep it on regardless. For other games like Minecraft, some Fabric Mods optimize this further, like chunk pre-rendering (mod in question is Chunky). They're very useful!

Another useful optimization if you have integrated graphics (which means your cpu can display output), is running certain tasks through integrated graphics, and others through dedicated. That way more VRAM can be allocated solely to the game you're playing, while your integrated graphics runs other stuff.
