Hi everyone,
We have noticed a handful of reports from players saying they are experiencing what appears to be a stuttering effect in game. This looks visually like a low frame rate, however the game itself it running at a much higher frame rate.

This issue is caused by a change in how often the physics system updates in the game, this was changed to help optimise the game further on lower end machines. But created a stuttering effect on higher end machines because of the difference between the physics update and the frame rate on screen.

After a lot of digging around, we believe we have found the issue and a possible fix.
However because of how critical this change is, we would greatly appreciate feedback on this possible solution and how it effects players experience within the game.

This experiment allows you to manually change the rate at which the physics updates. Of course changing these too much can have a dramatic effect on the game itself. Please follow the instructions below carefully.


If you are interested in checking this out and how you try this solution, please check out the following instructions.

Downloading the experimental build
- Open your library and locate Jalopy
- Right click on Jalopy and select "Properties"
- Click on the "BETAS" tab
- In the drop down menu, select "frameratetest"
- no password needs to be entered
- This should trigger an update

Setting launch options

- Open your library and locate Jalopy
- Right Click on Jalopy and select "Properties"
- In the general tab, click on "Set Launch Options"
- type in -fixedTime 0.01
- This will trigger the physics at 100 times a second (100fps)

We recommend trying the following numbers for certain target framerates

30 FPS - fixedTime 0.033
60 FPS - fixedTime 0.016
90 FPS - fixedTime 0.011
144 FPS - fixedTime 0.007

Please note that any changed outside of these can cause unwarrented effects. If you experience any issues, please remove the launch option for the game.
Please note that further
