It's possible you have antialiasing forced off in your graphics driver settings

try tv_autorecord 0

host_thread_mode 0

one thread was probably good

remove the spaces around the =, also if you're on the verylow preset you need particles=low or higher, or cl_particle_batch_mode 1.

yes, but it makes a lot of of the other scout melees have that draw sound also:

There's a reference to it in the particles/explosion.pcf (and particles/explosion_dx80.pcf) present in stock tf2, not sure if that's what the error is stemming from though

here, same method as the stock original sound one, which isn't really ideal. unfortunately it also changes the sound of some of the other demo swords in addition to the scout sword, I don't think there's a good way to prevent that since they all share the same sound

also I didnt test it at all so if it doesn't work right lmk and I will fix it

sending a fake user agent achieves the polar opposite of whatever you seem to think it does

for what purpose? i don't think anyone does that

I meant what screen resolution for tf2, since the relative size of crosshair scale 32 compared to everything in the game you're trying to measure differs based on that

sv_pure reverts the custom flat textures back to the default textures like it's supposed to, but for whatever reason the texture size/resolution stays the same as that of the custom ones, which is like 1x1 or 2x2 or something for flat texture mods. the default textures scaled really small and tiled end up looking pretty flat, but if you look up close you'll see a 'grid' effect. technically it isn't bypassing sv_pure but it's kind of a grey area or bug or whatever I guess

you can, in four different ways, but it's not allowed

but bro youre not supposed to be allowed to use custom particles on sv_pure 2, and ignoring pure (regardless of how trivial it is to do) is against the rgl rules even if the particles wouldn't be

what resolution?
