SCUM - Sensitivity Calculation Incorrect

[revdox]

Hi,

i experienced some weird issues with the SCUM sensitivity. If you start the Game (or if you alt tab out/in) the initial sensitiviy is way off from what you configured ingame or in the config file. After a while it adjusts itself step by step. (after 2h of gameplay my sens dropped from 42cm/360 to about 48cm/360 - this is not affected by any wheigt system like in tarkov - tested with different mice)

 

Other than that:

For testing purpose i adjusted the actual FOV from Insurgency Sandstorm to the max actual FOV from SCUM (wich is 100). Based on that values i calculated the sens i have to set in the ini File in SCUM. The 360/cm is WAY off.

 

This should be aproximately the correct settings for 42cm/360 (your calculation seems to be something around 0.190000, which obviously is not correct)

scum.MouseSensitivityTP=0.145000
scum.MouseSensitivityFP=0.145000
scum.MouseSensitivityDTS=0.145000
scum.MouseSensitivityScope=0.145000
scum.MouseSensitivityDrone=0.145000
scum.FOVMultiplier=1.441200
.

.

.
scum.FirstPersonFOVMultiplier=1.441200
scum.ThirdPersonFOVMultiplier=1.441200
scum.FirstPersonDrivingFOVMultiplier=1.441200
scum.ThirdPersonDrivingFOVMultiplier=1.441200

 

 

Can you confirm that?

The sensitivity in this game is updated, so I need to analyze it again. Also note that the game has a lot of negative acceleration if you use 1000 Hz polling rate, I'll see if I can find a fix for this too.

thx for your reply... negative acceleration on 1000hz? can you specify that? i played all games on 1000hz till now... anything i should change?

A lot of Unreal Engine 4 games have mouse smoothing on by default. For some you can turn if off by adding some parameters to the config file, but this doesn't work for all of them.

With smoothing enabled 1000Hz will be severely affected and be way too slow. The only solution if it can't be turned off is to use 500 Hz or 250 Hz. You should notice a huge difference in SCUM just switching to 500 Hz, but I think the calculation is still a bit off. It should at least be stable though.

DPI Wizard... you did true magic to my SCUM experience.... you were absolutely right... changing the polling rate did also change the sensitivity....

 

now i added the following lines (read in a killing floor2 forum) to the Input.ini:

bEnableMouseSmoothing=False
bViewAccelerationEnabled=False

 

the inconsistent sensitivity is now gone and the game feels SOOO much more responsive when navigating through buildings in firstpersonview... although i dont know exactly wich one of these two lines did the trick (further investigating)...

 

can you explain me these two settings in detail?

I just updated the game with correct calculations and instructions on how to disable smoothing.

Also added scope, but the "All" calculation doesn't work at the moment so you have to do each aim separately.

bEnableMouseSmoothing add frames to smooth out the mouse movement. So instead of for instance moving 100 counts instantly in one frame the game might smooth it out to 2 or 3 frames. This causes a floaty and disconnected feeling.

bViewAccelerationEnabled is simply acceleration, so the faster you move your mouse the faster you move in-game.

wow i appriciate your fast support... the calculation is now correct (i manually set the sens to 0.120000 by measuring 42cm/360) and your new calculation is giving me the value 0.119859 which absolutely confirms my test...

you just added the bEnableMouseSmoothing=False to the SCUM description... so i dont have to use bViewAccelerationEnabled=False at all?

It doesn't do any difference in this game, but if you ever have issues with Unreal Engine games it always worth a shot adding it

The "All" conversion is back for SCUM!

so everything is now ready for the upcoming big 0.5 scum patch...  well done sir....
