It's time to let go, folks. Windows XP is truly on its last legs.Confirmed by Square Enix Community Manager Mike Oldman, Just Cause 2 is incompatible with DirectX 9. Here are the system requirements, shamelessly cut and paste from Steam's Just Cause 2 page:Minimum:- OS: Microsoft Windows Vista (Windows XP is unsupported)- Processor: Dual-core CPU with SSE3 (Athlon 64 X2 4200 / Pentium D 3GHz)- Memory: 2GB System Memory- Hard Drive: 10GB of free drive space- Graphics: DX10 compatible graphics card with 256 MB of memory (Nvidia GeForce 8800 series/ ATI Radeon HD 2600 Pro)- Sound: 100% DirectX 10 compatible sound card- DirectX?: Microsoft DirectX 10Recommended:- OS: Microsoft Windows Vista SP1 or Windows 7- Processor: Intel Core? 2 Duo 2.6 GHz or AMD Phenom X3 2.4GHz or equivalen- Memory: 3GB system Memory- Hard Drive:- Graphics: DX10 compatible graphics card with 512 MB of memory (Nvidia GeForce GTS 250 series/ ATI Radeon HD 5750 series)- Sound: 100% DirectX 10 compatible Dolby Digital 5.1 sound card- DirectX?: Microsoft DirectX 10.1Developers are finally leaving the aging OS behind in favor of Windows 7 (and Vista, as much as someone is capable of being in favor of Vista). It has had a good run, and was reliable beyond what almost anyone was expecting, but XP is tired and wants to rest. It's time to move on.
