I have to just laugh at the people who keep saying "it's your fan" or "it's the weather"
Listen - I've used a PC to game for well over a decade now, I know how to maintain a computer, and I'm more than able to keep a PC at well below standard "cool" temps.
Now - that being said, and I've repeated this SEVERAL times now. I can play Crysis on damn high settings, and not even remotely hit the same GPU temperature as I do while on Xsyon, let alone under 100% fan use..
Someone claims Xsyon hasn't revealed the "required system specs" yet here they are, sitting in the FAQ:
8.) What are the system requirements?
Windows (XP, Vista, Windows 7)
Processor: Intel Pentium 4 3Ghz (or similar)
RAM: 2GB
Video: 512 MB Video supporting Pixel Shader 2.0
Hard Drive: 10 GB
Of course we recommend the best system possible!
So - being that I have WELL over the required system specs (I'm running dual core 2.5ghz + 8800 GT OC'd) and I can play any other game out without touching even remotely the same GPU usage and temps, I'm left pointing the finger at Xsyon.
And no, the OC on my card is not the problem, my card runs at an average 60-70 while under heavy loads on other games, with maybe 50% fan..
My 8800GT runs at 80-90 under 100% fan on Xsyon - this is not right, no matter how you spin it.
