Run-flat tires that come standard on some BMWs are not airless - they just have reinforced sidewall. They still can deflate due to a puncture or a cut, but afterwards they can get you home (up to 150 km at speeds up to 80 km/h).
Installer tries to extract RO.lgh (and rest of game contents) regardless of what level of license do you have, there are no separate demo/S1/S2/S3 installers.
I can't help but disagree - Core i5-8250U of my $600 laptop handles LFS without no issues whatsoever, it's the Intel IGP that's bottlenecking it a little bit. I get around 60-90 fps, but that's with no antialiasing. CPU usage on a single core never goes above 50%, though, so if I had a dedicated GPU, I reckon it could go well above 120, and that's with a full grid of cars on a laptop.
I mean, unless you run random .exe's you grabbed off piratebay, or got in an email attachment from a Nigerian prince, or found on a USB drive dropped near your office, you're probably going to be fine without one
For those with NVidia Optimus on Windows 10 who can't get 0.5F2 to use NVidia dedicated GPU: it's a known `bug` with Optimus not really supporting DirectX 8 properly.
