. Most "Highly Compressed PC" versions are fake because a native PC version of the game does not exist. Common Risks of "Highly Compressed" Downloads
Extreme compression only achieves small file sizes by stripping out high-resolution textures, audio files, radio stations, and pre-rendered cutscenes. Even with brutal gutting, fitting the map, car physics, and core engine of Forza Horizon 2 into 500MB is technically impossible. The Massive PC Problem
Do not fall for the "500MB Forza Horizon 2" trap. It is technically impossible for a game of this visual fidelity to be compressed that small without losing essential data.
Wait for Decryption: This is the most critical step. Because the file is so small, your CPU will work hard to unpack the data. This can take anywhere from 30 minutes to 2 hours depending on your processor speed.
The most common scenario. The file is an executable (.exe) designed to infect your computer with viruses, steal your passwords, or log your keystrokes.
Forza Horizon 2 was never officially released for PC. It remains a console exclusive. Therefore, the only way to play it on PC is through (which is still in early stages) or Xbox 360 emulation (Xenia) .
Legitimately rip the ISO file from an original Xbox 360 game disc using a compatible PC disc drive. Run the uncompressed ISO file through Xenia.
