Hi. My friends and I have been wondering if it's possible to disable fog and other special effects in order to improve performance. Any other tips will be appreciated too.

To improve performance try this:
- Open winsetup.exe
- click 'Advanced' button
- up RAM limit to 100mb and 'Save' or 'Save and Run'

I've been trying to run The Cat Lady on low-end (from AGS perspective) machine - single core Cortex-A8 ARM 900 mhz 256 RAM machine (Nokia N900, debian-derived Maemo operating system), via AGS compiled for armel. It succeed, but is utterly slow, and I haven't observed noticeable performance gains by disabling any effects, either via command-line or during-compile parameters (except for disabling sound, which made it few times faster - yet still not playable, not to mention, that playing such game without sound is pointless).

So, from perspective of my experiences - AGS is so resource-heavy (relatively to things it render), that either you run it on system that is enough to handle it, or you may skip tweaking attempts, as it won't help (unless problems are created explicitly by messing up with configs).

The AGS is optimized to run on computers, I don't think you're going to have much luck in running the game on a smartphone, as much as it more than meets the minimum requirements the game asks of a computer. The game runs, but there's absolutely nothing you can do in order to make it do so smoothly and in a playable fashion, unless the publisher releases a smartphone version.

I think it is the game itself. AGS doesn't seem to be that heavy with other games...

Well, if we leave fubar systems (Android, IOs, Windows Mobile) out of the equation, "smartphones" are nothing different than mobile computer (notebook/netbook), just on different CPU architecture (even the latter not entirely valid, considering latest attempts by Intel to make a small breach into armel-dominated mobile universe). Of course, the former requirement (no lame operating systems) filter out 99% of "smartphones" and tablets in the world ;) but I'm blessed with using mobile computer/phone combo powered by real GNU/Linux operating system(s). Indeed. I'm not knowledgeable with AGS, but R.Michalski mentioned using "custom installed AGS modules" (for parallax and such effects), so maybe my compilation of AGS isn't optimized for TCL. Indeed, other AGS games (apart from slowdowns caused by some glitches in AGS<->pulseaudio cooperation) aren't taxing device so much.
