The irony is, a number of people think it's a competition, even when it's not, and it's mostly not. So they feel a kind of satisfaction, but never realize the majority of gamers build systems capable of running only what they need, and not necessarily all games/apps, in their highest settings. I'm one of them, I could have built a much better system, but I decided to wait, and invest in my car, and now I have more options for building. Although I admit, if it didn't matter at all how much I spent, I'd probably re-build every year with the best hardware, but I don't think I'd get off knowing I had the best performance..lol.
Its definately better to have consistant smooth FPS than sporadically super high and average at different points of the track.
Ive found the best setting is leave FPS uncapped but turn on vsync and itll match to your refresh rate automatically even tho it goes over 200fps uncapped.
I honestly believe a solid 200fps is noticably better than a solid 100fps even if refresh can only be 100 but a *constant* solid 100 is much better than it fluctuating between 50 and 200.
I have a Samsung SyncMaster 959NF 19" CRT monitor which is capable of doing 2048x1536@60Hz. LFS is very playable on my PC even at that resolution. Normally I play LFS at 1600x1200@85Hz.
