unexplicable low framerates on linux distros when switching from 1.4 to 1.5beta1

[nailikmooc]

Description

I tested stk 1.5beta1 on an Acer Aprire 7 laptop with a NVIDIA GTX 1060 graphic card and multiboot system with Windows 11, Kubuntu 24.04 and Mint 22.0. All 3 OS have and have STK1.4 installed and 1.4 run with framerates > 100 fps. On Windows 1.5bata1 also yields also a framerate > 100 fps, but on Kubuntu and Mint the framerate is only between 25 and 30 fps. The stk 1.4 installs on Kubuntu and Mint (tested with installation via distro and and with official the tarball extracted into a directory) yield framerates > 100 fps. The max frame rate of the 1.5beta1 installes is the unchanged defauld 120 fps

Hi. May I ask what graphics level are you using?

@nailikmooc Try reduce max-bones from 2048 to 1024 in stk-config

I'm pretty sure it's because when running via run_game.sh, it's launching on the integrated graphics, while when running 1.4 from the launcher, the PrefersNonDefaultGPU=1 option in the .desktop file makes STK launch on the dGPU.

It might be worth replacing run_game.sh with a .desktop file, so users using the official binary have STK properly launch on their dGPU.
