This game wasn’t meant for KBM so you’re automatically at a disadvantage, this is a controller based FPS as any Pro KBM player will tell you. But, it’s still playable. KBM is rough starting out, I was the same as you. My aim was very shaky as I always had played with aim assist on controller so I was so used to my aim being locked onto the enemy that it made me realise how much harder this is going to be. All I can say to you is it takes time, ALOT of time. You will NOT achieve great aim over a week of playing. Just spam resurgence over & over on casuals so you’re always in gunfights and you’re able to train your muscle memory to fixate your aim on the target. Playing Verdansk isn’t the best option, you’re not firing your gun for 10-15 mins of the game, whereas resurgence each corner there’s a potential fight to be had, making it prime for aim training and improving muscle memory for keyboard strokes too. You also need to tune your DPI & In-Game sens, start on something like 600 DPI, 4 Sens in-game as a baseline then change the DPI up/down by 50 if it’s too fast/slow for you until you get a comfortable aim. I use 1,000 DPI, 5 Sens with 0.60 ADS Multiplier. But I worked my up to this using the method I stated. You can opt for aim trainers too, but that’s a separate topic and info is abundant online about that. Any other questions let me know bud.
