Lately, I've been trying to figure out why my graphic performance isn't what I would've expected a 4670 to perform at. I had gotten a whole new system, except for the hard drive and dvd drive which are (I think..) still good. I think I've ruled out the possibility of the CPU being bad, and I don't think the ram is bad in that I haven't have a critical error, BSOD's, or any sudden reboots while idle or under load. I also upgraded my power supply, and at first I thought the problems I was having with my graphics card were because it wasn't getting enough power, but I upgraded again from my current PSU to a Corsair 750Wtx power supply, and it didn't help.
The problem that I'm having is that I'm running Flight Simulator X, and it looks pretty good and everything, but I installed an add-on called Real Environment Xtreme, that changes the look of the clouds and the sunset/sunrise daylight, nighttime, basically. On some of the clouds, it works fine, I get around 25 FPS and everything, but once a big cloud (usually in a thunderstorm or overcast) comes into the picture, the frame rates plummet down to 5 or 6. And sometimes, when I pan the camera around the aircraft (makes it generate a lot of scenery, which is heavy load on both the CPU and GPU) it generates a couple of artifacts here and there, not too often, and only for split seconds. The thing is that I don't think it's the CPU that's not capable since I can look at the scenery and set it up to max (which is what drives most computers insane) just fine, but when I get to the graphics part of it (the heavy clouds) my frames drop drastically.
Also, there's a youtube video where it shows another user that has nearly identical specs regarding CPU speed and GPU, and his flight simulator runs perfectly, with Real Environment Xtreme put in there. This is what lead me to believe that my system isn't performing to its capabilities. Also in the support forums for Real Environment Xtreme it shows other users that have slower CPU speeds or lesser model video cards being able to run it just fine. I also tried lowering my resolutions from 4096x4096(HD) to 1024x1024 and it's the same thing, when I look at the big clouds, rates drop.
The thing with my motherboard though:
I have: http://www.newegg.com/Product/Produc...tent-_-text-_-
I was trying to get it overclocked past 3.6 ghz since I have decent temperatures, to around 3.7 or 3.8 but once I go even a hair above 3.6 it just doesn't want to go anymore. I've tried increasing CPU voltage, NB voltage, HT-link speed, everything and nothing seems to work to get it higher. I don't know if it's the motherboard unwilling or what, it just didn't go.
Does anybody have any suggestions as to what could be my problem?
