assuming you're not just like, missing, here's some basic troubleshooting i can think of:
-try running directx 9 (some people report issues of the game lagging with directx 8)
-try low instead of very low (very low can also make the same run worse)
-make sure vsync didn't weasel it's way on
-check your drivers for updates
if none of that works, file a report here

a very long time ago i used to suck ass at the drums

let me know when scout gets the stickybomb launcher

it's called invite highlander

during the ramadan update heavy can't eat sandviches on daytime maps

i like 5cp maps nobody really gives a shit about anymore like fastlane, yukon, coldfront, etc
you wouldn't really play them in a competitive setting anymore but i still like them :)

I'm not very good at Soldier but it's not super hard to hit gardens, and much better jumpers than me can very easily hit gardens. You can also just switch to rockets if you miss or think you're going to miss and get some damage or frag whoever your target is, usually a Medic. It's not like Sniper or Spy where you have to give up a Scout or Soldier to instakill someone, you're just attaching an instakill option onto someone with one of the best weapons in the game and incredible movement. If you fuck up, you still have the Rocket Launcher.

Hopefully your Scouts are still shooting the flying guy out of the air, but sometimes they just can't or are... basically AFK

I personally have a great dislike of invasive anti-cheats, and some of us run operating systems that have serious issues even running them. Also, this was before my time, but I'm fairly certain when ESEA ran TF2 someone snuck a Bitcoin miner into the client at one point. That's unlikely to happen with a hypothetical RGL client, but I'm still wary.

Really, I'm not sure why invasive anti-cheat is even needed in a relatively smaller league that supposedly has people reviewing demos weekly. There's not a ton of money on the line anyhow, I don't want RGL to get giga access to people's computers over it. Also, if RGL supposedly can't afford to host demos, they definitely could not afford to run a system like FACEIT.

i'm fairly skeptical of the notion RGL somehow can't afford hosting demos. demos are not large files like videos, they're just recorded server instructions. i know there's hundreds of players, but even then it cannot be that much storage space. if it's a paid league they can use some of that money to actually do what people want, no?

i know RGL runs at a loss, but cutting the already rather small prize pool down for a season or two to just... buy hard drives, or cut the prize pool a bit each season to rent cloud hosting space cannot be that egregious an ask. i think people can stomach that to not have to deal with guys blatantly walling or toggling each season.
