Fully clean up your TF2: https://github.com/mastercoms/mastercomfig#clean-up

What's your up/down speed?

Not reaching the FPS cap is fine. That's just there as an upper bound to prevent some possible glitches with an unlimited FPS cap.

Having a lower FPS cap is personal preference, like if you want a stable framerate or want to prevent overheating, as sage mentioned.

6.4.0-b1 https://github.com/mastercoms/mastercomfig/releases/tag/6.4.0-b1

It just reuses prediction data from the previous frame that can be slightly off for the server.

That value comes from 1.5 / 66. This is so that you aren't always relying on one snapshot to make it to your client on time.

Yeah, the interp in my config is low enough for it to be good for projectile classes while still being reliable enough for hitscan.

I think restarting the game in between with the addon and without would get rid of any performance boosts from caching.

cl_interp 0.02273 will only be used if cl_interp_ratio is 1. If you set it higher, it will set cl_interp to 2 / 66, 3 / 66, etc since they are higher values. Setting the interp higher is useful if you have a lot of dropped packets and lag.

How many times did you run the benchmark? And in what order?

Glad to hear that! Thank you for the kind words :)

What are your launch options, and could you launch your game with -condebug +cvarlist and then share tf/console.log with me?

It's not quite dxlevel 81, but it's sorta close:

mat_phong 0 // Disable phong for flatter shading
mat_disable_lightwarp 1 // Disable light warps
mat_reducefillrate 1 // Simplify material shading and use some DX8 features
mat_hdr_level 0 // LDR
r_cheapwaterstart 0 // The distance at which transitionary cheap water starts. Has less reflectivity.
r_cheapwaterend 400 // The distance at which fully cheap water starts. Does not reflect or refract and it is solid
mat_bumpmap 0 // Disable bumpmap materials
mat_specular 0 // Disable specular materials
r_shadowrendertotexture 0 // Do not use two materials for shadows

also, you can add this dxsupport_override.cfg into your custom folder to set a few commands you can't set manually.

6.3.0 released with networking improvements, performance optimizations, documentation updates and bug fixes

Also there's a new website https://mastercoms.github.io/mastercomfig/.

What are your hardware specs, OS and config?

I believe it is a bug with OpenGL versions of TF2.

That's what the cl_interp_ratio settings are for.
