There is backstory here to explain why I found out this information. You can simply scroll to the bold text near the bottom to get the intel you came here for. This is particularily for Nvidia users because I don't know much about AMD.. but I figure this works for you guys too if your CPU operates similar to mine.
Mobo - Gigabyte Z58-UD3H-B3
16 Gigs of Patriot gaming RAM - 1333mhz
GTX 660ti upgraded to GTX 760 before Clans
Intel i5-2500k (speeds vary from 3.3 to 4.5)
I'm posting to share with everyone, in the event that you, a friend, a unit member.. or anyone you find who is having FPS stability issues with MWO. This is an opportunity for you to help them if they carry a CPU similar to mine. Now... there is in honesty quite a list of things that can cause MWO to have mad FPS drops when critical moments require those frames. Some of you may laugh, shake heads... but there are times that people like myself can overlook/ over analyze a problem with our computers. We think they are broken in some shape or form when honestly.. its simply us users and our ignorance/ forgetfulness.
I had a 6 month break from MWO, and played Diablo 3's expansion like the hermit I am until a couple weeks before Clan Wave 1. To my knowledge MWO ran ever so smoothly.. headshotting ravens at full speed and being called a cheater for it (got vids). This was also shortly after DmC was released via Team Ninja, because my recently upgraded mobo died. So when I got it replaced, I did my thing getting my computer rebuilt and all that fun... I had additional computer problems, played with my bios, overclocked my rig and all that stuff. However there was a very new USB technology that was added to that timeline of mobo's. And little did I know that there was a feature enabled in my bios that was causing MWO's FPS stability to go haywire for these past 16 months. the 64 bit, HUD (somewhat) optimization and other fixes have certainly helped my GTX 760 from dropping to as low as 12 fps (for real).. until last night. I was talking about SLI with a friend, and it me that I haven't checked my PCI-E's performance since I last had 2 cards in my pc. I only use 1 unless I need more power.
Sure enough while playing GTA-5.. my Nvidia details said my single gpu was runing at 8x 2nd generation. So I did a little reading.. and this is what I learned;
Sandy Bridge (2000 series) in particular, supports USB 3.0 Turbo. Unlike Ivy-Bridge (3000 series) my i5-2500k can only support this function via using the mobo's first PCI-E's port. If your tower/ mobo has/ supports USB 3.0, you need to go into your BIOS and turn off the "TURBO" feature ONLY. Your USB 3's will still function, just not at the expense of PCIE x16.
I couldn't believe how consistent my gpu was staying above 50.. now I can do Terra Therma on max in Training grounds and hit 110.. but the consistency I was getting when I gpu was running on 16x was like re-experiencing when I first built this former beast machine.
Final Note:
There is a price for this towards a game exploit. Alot of people with not-top-of-the-line pc's don't know that the more players are in your visual cone.. the more your frames drop. You can find clumps of enemies this way because your visual obstruction has nothing to do with the way the game communicates within its code.
All in all Im happy to share this new experience with everyone. And for those who look into it, I hope it gives you the results you are looking for.
