FPS Limiter is in no way connected with refresh rate. Only by looking at default 150 value that can be clear

(so far, none of the LCD displays can refresh themselfs at that rate, simply because crystals can't change that fast = physical limitation). But you made me curious to see if it's actually somehow connected, and i tested with refresh rates up to 160Hz, down to 60Hz.

Lightmaps up to 'default' quality are automatically saved in the track file itself, and you can choose to generate/use higher quality lightmaps that are saved in the cache using these settings. Virtually no effect on performance on any modern system, as DX9 is already in the realm of quizzical. Only performance wasted is load times..
I'm not sure if that setting is in any way connected with game mode (a bit absurd...). But anyway, I've done testing, and it really makes no difference in performance (unlike on TMF), also it is connected with wehicle reflection as far as i know from TMF. Didn't tested in more scenarios to be 100% ertain, but as far as it goes, you are right, it make no difference on current settings i use. Load times are fast anyway... 1-3 secs at max.

Depending where is bottleneck on one system, it can make difference. Allot of factors make tole here, for example, target FPS, if with "modern system" at high settings, targert FPS is over 200, then it will make difference. It really depends from more factors. I don't play TM below 120FPS (as minimum), avg 200 or more, with high settings.

The moral.. if you don't know what it does, don't touch it!
With your system, should be able to start out with default settings, max them out, and run without any problems. If that's not the case, must be something on your system causing a problem (key-pollers, im programs, DLNA servers).
Why he should not touch compatibility settings??? I don't understand that logic. There is no way he can do damage to hes system with those settings. IF you like to experiment and learn, play with all settings developers gave to you (it is very rare at this time), worst that can happen is that you will learn nothing from it

.
When is more then obvious that no one can actually find out what is wrong on one system without investing more time to it, and actually sit on that system and check it in person, best way to determinate what is the problem is fot him to play with the settings (learn about it) and find out on it's own with help from community.
