Right click camera control - Linux

[bobbinhoppin]

Hi all, I've been trying to fix this since I started P99 4 months ago, but I finally give up to come ask for help.
I'm running P99 on a Dell Latitude E6410
Operating system is fosspup64 9.5 Linux Kernal 5.4.53 running Xorg 1.20.8
Video card is Nvidia 3100M PCIe 512MB driver is 340.108

Problem is in game, using the right click to change camera angle is choppy. Otherwise I don't get lag usually, but the appearance is similar to lag. With enough bumping, twitching and jerking of the mouse, I can usually get the camera where I want it (yes, the "Mouse Look" button in Options->Mouse is clicked down yellow).

I have tried changing the in game settings every way I can find. Particularly I want to try adjusting the Max. Frames Per Second, but whenever I do, it reverts back to 60. Is this the same as the refresh rate of the screen, which is set to 60 (or 59.99) Hz in the Nvidia control panel?

I have tried WinEQ2 but struggled to get it working in my 64bit Linux running 32bit EQ through the program called wine.

TIA
