Wow... What a gorgeous, if currently unplayable game! The same as others across the globe, I am having massive issues with Crash To Desktop, micro stutter, unpredictable fps & slow downs.. I can see there are many, many Youtube videos about it, but it's a truly horrible experience ruining an otherwise great game.. I am also experiencing massive slow downs after about an hour playing, as if the game engine goes in to a bizarre slow motion mode (like you are jumping in low gravity?) Performance Logs show CPU & GPU usage fall dramatically while in slow-mo mode, then I have to close & restart game. No other games I own show microstutter or slow downs at all (i.e. Doom in "Nightmare mode" gives me 130-150fps solid (depending on environment complexity !) so this is very frustrating to say the least... For reference, I'm running an 'i7 3770k overclocked to 4.56GHz, 32GB RAM, 1TB SSD & a GTX 970 FTW (Running @1565MHz) Windows 10. Latest Nvidia Drivers 372.54 (15th Aug 2016) no better than previous driver. Logs show my system at no point is getting over stretched, so horsepower is NOT the issue... Mix this with ALL online functions are not available if you don't use the GOG galaxy client (which is "effectively" DRM if you want FULL game functionality) and I am left feeling largely deflated. I asked GOG in a support call if this was going to be the case before release, and they didn't answer my question, they told me to ask Hello Games? which was no use, and they should know these things! I have a Oculus rift & HTC Vive (Thanks beautiful wife, you're awesome!) and I very rarely get motion sickness from either, however NMS microstutter IS giving me motion sickness, that's how bad it is!! So this better get patched and working or I am asking for a refund soon and will rebuy & retry this game after a year.. As this is definitely not "Working, Guaranteed" its currently, "MicroStutter & almost DRM free, Guaranteed" - My first & hopefully last GOG disappointment.
