There are a lot of topics about sensitivity and mouseaccel. I've tried to organize these parameters into 3 groups.
1. Low sensitivity (20+ cm - full 360 degree turn) without any accel
Eg.: fox, toxic
+ Movement of crosshair completely corresponds to movement of hand;
+ High precision with MG/LG/RG;
- Slow complete 180 degree turn;
- You can get tired over the course of the game;
- Requires large mousepad;
2. Middle/high (10-20 cm - full 360 degree turn) sensitivity without any accel
Eg.: Rocketboy
+ Movement of crosshair completely corresponds to movement of hand;
+ High sensitivity benefits for weapons like RL/PG;
- difficult to improve accuracy with RG/MG for long distance;
- Shaft becomes warp;
- In important games weapons may be "broken" 'cos of nerves.
3. Middle sensitivity (3-5) with low accel (0-0.5)
Eg.: Akiles, Purri
+ 180 degree turn becomes more quick;
+ Shooting becomes more stable;
- Movement of crosshair NOT completely corresponds to movement of hand;
- You can get excessively tired over the course of the game.
4. Low sensitivity (2-4) with high accel (0.5-2)
Eg.: LeXeR, Unkind, Cooller (most russian players), Fatal1ty
+ The quickest complete 180 degree turn;
+ You can easy make shots at all angles;
- Movement of crosshair DOESN'T corresponds to movement of hand;
- Requires more time to practice.
As always, each player selects his *OWN* combo of sens and accel. The differences in Windows sensitivities, mouse drivers, and the mice make parameters different for each player.
GL & HF to all :)
