If you're using the overlay, try turning it off. Seems to be the thing that causes the most issues with mumble.

You can use this mouse in either wireless or wired mode. According to the threads on overclock.net the mouse has a ~ 1 ms delay between wireless and wired mode (1.2ms according to logitech's CPate). Wired apparently the performance is the same as the g303 and g502. I'd imagine that could increase in non ideal situations but a 1ms delay is really not going to do much. The shape is way better than most other logitech mice and the weight is pretty good considering it has to have a battery.

The main problem is the crazy price which makes it completely not worthwhile. I wouldn't be surprised if they brought out a cheaper wired version down the line or the price drops though.
Damn I got ninjad but yeah.

You could kind of apply that argument to gunboats as well though and I'm sure when they came out people
There's way less of a contest between gunboats and shotgun than there is between booties and pipes as well.
I think the issue most people have is it can be used as a crutch if you aren't very good, but I think they could end up changing the role the demo plays like we've seen with gunboats pocket. Removing airpipes does suck though.

I agree with this for this year but there's no reason iseries has to be the biggest event going. In some ways it's good to have competition between lans because there will be more incentive for sponsors to offer higher prizepools to make their lan the important/prioritised one. I'll take what we can get at this stage but if TF2 gets bigger iSeries really isn't a big deal as lans go and Dreamhack is probably a bigger name in terms of making the game look legitimate.

Might be worth mentioning the date of the actual DHS lan in the OP which is 18th-21st of June which is sick because my exams finish that week, although I might have one on the 18th which would kill actually going.

How did sheepy manage to make this thread even worse than it already was?
I'm not even mad that takes some talent.

Most mice are relatively durable and should function for a couple of years, allowing for feet replacement. Most mice that have issues that cause them not to work (Like some of the logitech ones with the dodgy cable) are normally reported and found out pretty early on.

The two mice I've used with the best feeling build quality are the Roccat Kone Pure Military and the Mionix Castor. Both feel very nice to hold and have good button presses.

KPM needs to have its firmware updated to the latest version to fix bugs with the mouse and the shape is something some people might not like, might throw mouse's balance off for some people. This mouse does have really nice buttons and a great scrollwheel and feels really comfortable (imo).

Castor is more expensive, has less clicky feeling buttons but a very nice material. It's probably nice to palm but has 2 finger grooves on the right hand side which force your finger positions which made it uncomfortable to aim in game with for me although palming it for desktop use is nice.

I've also heard good things from a quality and price perspective about the EVGA Torq X5 if you're into ambi mice but it does have a glossy coating which most people don't like.

I don't think the issue here is actually the shape of the hitbox though, the jittering in and out would still occur if the collision hull shape was changed because that's the only way I can think of stopping players getting stuck inside each other. Changing the bounding box to be a smaller cylinder would also probably make hitting projectiles a lot harder and scouts even better than they are already. I'm not sure I'd want valve to fuck with that.

Yeah pretty sure collision hulls are what calculate this so it's wider on the diagonals etc. You can kind of test it by wing into a player standing still and strafing and seeing how you slide around them.
I have no proof the game actually does this, but I think it's logically how they'd stop people from getting stuck inside each other. It just comes from having to play really gay with movement on scout when I was on a shitty jittery laptop and couldn't aim. People accused me of ratehacking a lot. The main problem with doing this is that any decent scout will kill you before you get into the ridiculously close range you need to do this.

This is how hitboxes in TF2 interact. If you walk into someone and get inside their hitbox, you'll be pushed out so the hitboxes don't overlap. It's most noticable on scout because you can get into their hitbox quickly before the game realises due to the fast movement speed. You can actually use this to your advantage on scout on low ping by tapping w when you're at very close range next to someone to repeatedly jitter out of them. Because it's you that's being displaced it makes your model really jittery and hard to hit, although this is mostly impractical in actual games.

The interaction does change with ping though. I think because the game takes more time to realise you're inside someone you can actually get through the middle of them and you'll get pushed out in a different direction which is why you can sort of slide through other players on scout at higher ping. You can't use this to your advantage too well because you kind of get teleported randomly and aren't looking in the direction of the player when you come out the other side.

I can understand cultural appropriation being a problem if you're really misrepresenting a culture in a bad stereotypical or cringeworthy way by doing it, but most people seem to get really upset over stuff that really doesn't matter.
e.g. I know a white guy who wears African shirts and acts like they're down with people from Africa even though he doesn't know wtf he's talking about and says shit like "oh you're from x country you must love this shit". There's nothing wrong with him wearing the shirt in itself but all the other shit that comes with is kind of cringeworthy and I can imagine it could really piss people off.

On the other hand acting like "my culture trademarked this, you can't use it" is stupid in most cases. People have been stealing ideas for clothes/tools etc. from each other's cultures for millenia because either they thought it looked cool or it was functional.

TF2Center drama is the worst kind of drama

It's also worth trying to stream in games that aren't tf2 and seeing if the frame skipping/input lag issue persists. If they don't it might be something to do with TF2. There are some optimization commands related to cpu/gpu usage. Might be worth checking those out or getting rid of your config and testing on default settings.
If you're really stumped, r0ach on overclock.net also has a guide to optimising mouse input for windows. A lot of this I think is placebo and doesn't actually help. I wouldn't reccomend fucking around with the bios settings, but the software section as well as the win 10 section might be worth looking into, don't count on it doing anything though.

I'd suggest fucking around with your graphics card/display settings in Nvidia control panel. Issues like this seem like they're more likely an issue with graphics card settings. Pre-rendered frames (lower if possible) might be something you want to look at as well as display scaling (No scaling might help). Also try updating or rolling back graphics card drivers.
