I don't have Terra Lander 2, so I don't know if it has the same frame limiter bug. Has anyone else played the sequel?
Meanwhile, I installed and tested a bit the sequel, "Terra Lander II: Rockslide Rescue".
The game features two options with respect to the frames per second and a frame limit, which can be found in the main menu:
>> System Settings >> General Timing and Performance
Option 1: >> automatic frames per second: yes/no
Option 2: >> Max frames per second clamp: 0...60 (in steps of 5, 0=yes on auto above)
I experimented with those for a while. On auto the framerate is all over the place depending on the amount of objects and particle effects visible on screen. Using a cap of e.g. 30 or 60 frames in the second option lead to a much more smoother framerate overall and less heat development on my notebook.
(But I have to mention, that I am using one of two power profiles limiting the CPU usage either to 70% or to 80% of its maximum.)
=> Does the first "Terra Lander" provide the same options in the setting, but they do not take effect (because you wrote: 'game does not have a working frame limiter')?
=> Or are comparable settings missing in the first place?
I have not tested to play the sequel in window mode, yet.
=> Does anyone know, if the frames of an application or game could be limited externally (e.g. by a operating system setting), when it is running only in a window instead of fullscreen?
=> Does it make a difference, whether or not the application or game is running in fullscreen or windowed?
(Playing older games utilizing the dgVoodoo2 wrapper I am having at least significant performance differences running, for instance "Pirates of the Caribbean" (2003) or "Search & Rescue 4: Coastal Heroes" (2003), in fullscreen or a window of equal resolution.)
