Image Space rFactor

Image Space rFactor is a race simulation game that has hyper-realistic graphics and sound FX that surround the senses. The game's second installment has been updated with real-time day and night transitions, improved daylight and nighttime scenes, realistic weather with heat waves and rain, more definition in the road surface while driving, and high-level aerodynamics. The cars received engine boosts, turbo modeling features, new tire models, and cockpit vibrations. This simulation software has been upgraded to work well with multi-core technology for faster game play. The rFactor series featured mixed class road racing in its first installment. Image Space Incorporated developed rFactor using its isiMotor software engine, which made use of an advanced physics engine (pMotor) and an automotive design engine (gMotor) during development. The software engine and its add-on components largely contributed to making rFactor the industry standard in simulated racing platforms.

a word of warning

Be careful not to rename the extension on .mas files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .mas. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
