Important to note that these are not viewmodel-specific. They apply to all models in the world

I think the OP's point is that we might as well go for having the game look nice rather than having it set up to give you the most frames/be the most aware of your surroundings. His argument is that there's no reason to use fov_desired 90, because we're simply the audience, and we're not having to react to things. Same way that we don't care about the broadcaster's game having more than the fps of the stream, so if they can handle dx9 and get 61 frames, we'll be happy.

It's just like how we don't complain about not having streams at 144fps, and for the longest time we didn't complain about streams at 30fps. As long as the actual players in the game are having an enjoyable experience, the audience is having an enjoyable experience watching them.

I think "all" might be a bit of a generalization.

Verify game cache, remove "performance" config/try performance config depending on if you already have one, remove mods, report back

please, this phishing technique is probably almost a year old by now, stop making PSAs about something that everyone is already aware of/at least search first

Your interp is the maximum of the following: (cl_interp) OR (cl_interp_ratio * (1 / cl_updaterate))

cl_interp_ratio is forced to 1 by the ugc config, so if you set cl_interp to 0 and are using cl_updaterate 66, your real interp is (1/66) = 0.01515151515

oh, THAT syncing problem!

Welcome to TF2! The only way this could happen is if you never launched the game before.

...why? How could that possibly be used as a cheat (especially since it's a server cvar)?

Locked in what way?

Not unless tf2 actually loads TrueType fonts now instead of relying on windows to do it.

You'll just get horrible texture aliasing.

Make sure you're not on WiFi. If you're already wired, call your ISP and tell them your connection quality is unacceptable.

Run memory diagnostics?

Most of the values you are setting are already the defaults for those cvars, and they remainder is almost all preferences that don't impact performance negatively or positively.

Trying not to derail this discussion any further, but you're right, and sorry you had to type all that out (I'm quite familiar with c++ and multithreading). I was just trying to explain that lack of thread affinity does not mean that tf2 can simultaneously use 8 cores.

On another note, I'd be curious to see if the results of your testing with different -threads values were different when using threadpool_affinity 0.
