Hello fellow Commandos

I had a bit of a problem, which I resolved myself after not being able to find the information online (exactly). So I am writing this in case anyone else experiences a similar problem and is a little stumped.

My issue was in Commandos Beyond the Call of Duty. Description as follows:

1. the game would play at 20fps locked (which is normal).
2. moving the mouse caused the FPS to rise as high as my maximum refresh (144hz in my case) as long as I kept the mouse moving.
3. While the mouse is moving continuously and the FPS caps at max, all scenes and effects in the game freeze to a single frame until I stop moving the mouse, then continues as normal.

### This gives the impression that there is stutter (very bad stutter) if you move the mouse in bursts.

The FAQ did say to play around with V-Sync, but I found the issue in my case was specifically to do with G-SYNC.

Having turned this OFF in the nVidia control panel (specific to BCD), I found that the issue completely alleviated itself.

Under "Monitor technology" I changed it to "Fixed Refresh", this causes the _Preferred refresh rate_ to automatically change to "Application-controlled", leave this as it is. If you set this back to another setting, it'll change your Monitor Technology back again too.

For good measure i have threaded optimization turned off as well regardless.

Now I can leave it at 144hz on the desktop and it'll adjust itself as needed in the game. This completely alleviated the issue for me.

Hopefully this helps even 1 soul out there.

I am unsure if it is worth seeing about GSYNC compatibility being mentioned in the FAQ, or if anyone else would like to try and confirm this (as I might be an exception).

For reference, my configuration is: i7-6700K, 980Ti, 32GB RAM on an XB270HU monitor.

All the best to everyone.

Regards,

Lazbot

Thanks a lot for taking the time to document the issue and solution!

I'll also link to another thread about the exact same issue:

https://www.gog.com/forum/commandos_series/mouse_cursor_doesnt_function_properly_in_behind_enemy_lines/page1

That thread also mentions that a high refresh rate mouse can cause the issue. Lowering the Hz of the mouse to 125 or similar low/legacy speeds can help too.

So to summarize both fixes:

- Turn off Vsync/Gsync in NVIDIA control panel.
- Lower your mouse's refresh/polling rate to 125 Hz.
