Every single game you mentioned has some sort of tinker step reported on protondb even though it may be marked platinum. Here’s the one for oblivion:

    DRI_PRIME=1 WINEDLLOVERRIDES="xaudio2_7=n,b" PULSE_LATENCY_MSEC=90 %command%

Or maybe it’s this one that the next user reported…

    DXIL_SPIRV_CONFIG=wmma_fp8_hack FSR4_UPGRADE=1 game-performance %command%

I personally don’t want to have to do stuff like that to get them to work.

Having played Doom, Oblivion, Blue Prince, and Clair Obscur on linux, I can tell you that the tinker steps are unnecessary. I have literally just clicked play and didn't need to think about it. This didn't require a bunch of manual setup to get to that point either; I installed Endeavour and it installed the drivers I needed, then I installed Steam as normal and it was like nothing had changed from my Windows install.

People will post their tinker steps for everything. It's often just to disable the steam overlay, or inject their own overlay, or whatever they think gets them an extra 2 fps. It's linux and people love to configure it their way, but honestly steam/proton handles it automatically 99% of the time.

These are almost always unnecessary. I have 460 games in my Steam library (most of them are popular games, including ones mentioned in the parent comment, not obscure indies) and all of them work great out of the box without command line options. That's a higher success rate than my Windows machine. For example, the latter command is for someone who wants to hack in FSR4 support on 9xxx AMD cards; this is for power users.

I haven't played most of those games, but I can at least attest that I could run Clair Obscur with no tinkering whatsoever. A lot of times even if some people had to tinker with a game, you will be just fine and not have to tinker.
