[quote=kp] a cheap one [/quote]

There's your problem

.

anything i can do to sort of deal with this cause i cant buy a new mouse atm

Make sure the sensor is clean. If the mouse came with software, doublecheck it and make sure it doesn't have accel enabled. Clean your mousepad from any dirt/stains. That's about it but in the future just save up and buy a good mouse

Yeah, the sensor probably sucks and can't track fast movement. I'm afraid that the only thing you can really do is get a new mouse.
Maybe check the used market for something that you can afford.

best bet is try a different surface, or use a higher sensitivity

[quote=snowi]try lowering your lod via software or using a little piece of tape

remove synapse. use interaccel

update firmware

wipe any dust off sensor

try a different surface

what mouse did you get?[/quote]
whats lod?

[quote=kp]so i got a new mouse a cheap one and i get in game,i boot up some mge and i tried to flick and my mouse just went crazy like it went the opposite direction what is this? [/quote]

You've reached the max tracking speed of your mouse. Mice react in various ways when this is reached.

Higher quality mice when they reach this point usually either stop virtually all sensor input or very slowly moves in the same direction that you're moving.

Crap quality mice spaz out usually having major jitter going toward the direction you were moving the mouse and then resetting to it's last known position or just flicking your ingame view straight down or up.

[quote=kp]has anyone ever had this problem?[/quote]

Yes, this used to be an issue every player dealt with in the past.

for example here is the max tracking speed of the WMO 1.1a @125Hz

Xtrac Ripper XXL 0.9 m/s
SS QCK+ 1.6 m/s
Xtrac Hammer 1.3 m/s
Custom Cloth 1.2 m/s

In comparison to the G400s from 2013 and Zowie FK from 2014 both had a max tracking speed of roughly 4.0m/s at 500Hz or 1000Hz.

[quote=kp] it feels like i can only move my mouse around very slowly if i move too fast its going to have a seizure or something,DPI is 800 and ingame sens is really slow relatively,whats causing this problem,anyone?[/quote]

Low Quality Sensor and/or USB poll rate is set to 125Hz when it could be 500 or 1000 and/or your mousing surface is terrible/dirty

Get a better mouse

Make sure you don't have dust/hair on the sensor.

Clean your mousepad as good as you can or get a mousepad with a better max tracking speed. In my experience mousepads with the best max tracking speeds tend to be Black Cloth with a slightly rough feel i.e. QCK or similar, for some reason mousepads that feel smooth are usually worse. Ex. Razer Goliathus Control probably has a higher max tracking speed than the Razer Goliathus Speed.

If your mouse has software that allows you to adjust DPI and or polling rate trying changing it. Most mice work best at either 400 or 800 DPI, if you're on 125Hz try 500Hz or 1000Hz may improve you max tracking speed by a small bit (WMO 1.1a at 500Hz goes from 1.6m/s on a QCK to about 2.0m/s)

mouse usb poll rate overclocking only use on mice that don't have software/ no on board controller otherwise it won't work. Really crappy and Really old optical mice do best at 250Hz or 500Hz.

Try using various mouse accel settings it was super popular back in the day with quake largely because people couldn't move their mouse that fast.
