GTA V only picks up larger mouse movements, and is jumpy?

[lost4468]

Firstly I've gone through all of the settings and believe I've set them all correctly, but on GTA V the aiming feels very jumpy. The minimum distance I can get it to move on screen is quite big :/ and the aim feels quite jittery when moving small amounts, very pixelated. I have my DPI set to 5700 on a G500, and I do not get this issue with cod 4. Here's the relevant config stuff:

Code: Select all

      <mouse_options_list>
        <mouse name="" id="0" mode="Aiming" buffer_size="1" filter="0.00"/>
      </mouse_options_list>

        <axis id="rstick y" label="">
          <device type="mouse" id="0" name=""/>
          <event type="axis" id="y" dead_zone="43" multiplier="13.34" exponent="1" shape="Circle"/>
        </axis>
        <axis id="rstick x" label="">
          <device type="mouse" id="0" name=""/>
          <event type="axis" id="x" dead_zone="43" multiplier="6.11" exponent="1" shape="Circle"/>
        </axis>

I found it weird that the acceleration is 1, but that's the value that brings it back to the starting point. I've tried changing the buffer size but it doesn't seem to make any difference.

It also does not pickup slight movements in the mouse, for example if I move the mouse a tiny bit which definitely generates reports and even moves the cursor in windows (and moves aim in cod 4) then GTA doesn't move at all.

I was wondering if perhaps it has to do with the fact that it's running at 250hz instead of 100hz? Maybe gta was written for the 100hz rate? I don't know.

Maybe the dead zone is too high?

[lost4468]

No it's correct, decrease it until it stops moving, increase it by 1? That's what I've done.

Edit: It's the refresh rate, I changed it to 100hz and all the problems seem to be solved. Guess GTA V handles controls in a unique way?

How did you change the refresh rate?

[lost4468]

I just launched emuclient with the following?

Code: Select all

-c PS3_GTAV.xml -p COM10 --curses --refresh 10 --subpos

It's definitely working because if I go to lower refresh rates the problem gets even bigger.

Thanks for reporting this.
I will set the default refresh rate to 100Hz in the next release.

[lost4468]

Cool man, what about adding an option to each config? Also I'll donate soon.

[Matlo]

I won't add this in the config, because a same config can be used at different frequencies: sixaxis/bluetooth=89Hz, sixaxis/usb=100Hz.
Another config file with controller-specific parameters seems better.

I suppose you are using the EMUPS3 firmware?
Does it give the same results with the Joystick firmware?

Hi! I'm new to this forum and Gimx.
I have the same aiming problem in GTA V. I'm using Win 7 and Gimx-serial. How do you change the refresh rate to 100Hz? I can't find a setting for it.
Should also mention that I'm on PS3 and I have flashed the Teensy with atmega32u4.hex. Is that the right fiwmware to use?
