I recently tried running the latest stable version of The Dark Mod (v. 2.03) with EAX support enabled and Stereo selected from the in-game options menu under Windows 10 Pro x64, only to discover certain missions install and let me get all the way to the "Mission Loading" screen, but cause portcls.sys to experience an unrecoverable crash; furthermore, the crash always renders the front two speakers (those used by a Stereo setup) to be permanently muted until I reinstall my soundcard drivers. The only way to resolve this issue is to turn EAX off. My system specifications are as follows: Operating system (OS): Windows 10 Pro 64-bit Processor (CPU): Intel Core i7 4770 @ 3.40GHz System memory (RAM): 24.00 GB Dual-Channel DDR3 @ 793.1MHz Hard drives: ​Hard disk drive (HDD): 2TB DellHard disk drive (HDD): 1TB Western Digital Solid State Drive (SS): 256GB Dell Video card (GPU): AMD Radeon R9 270 w/2GB memory Sound Card: Creative SoundBlaster X-Fi Titanium Fata1lity Professional
