Ok, so, since my last thread was locked for piracy (I wasn't promoting piracy or anything), I might as well make a new thread and be more straight to the point.
I got a 550Ti for xmas, ASUS 550Ti (The lower end one), and we both have exactly the same hardware bar the motherboard and RAM (RAM have same speeds/timings, I have more RAM and different brand. My motherboard is an AMD 760G, his is an nVidia 7025.)
My friend has a 1920x1080 monitor, and mine is 1280x1024.
The problem is that my friend gets almost constant 60FPS in MW3 at 1920x1080, and I pretty much get constant 40-45FPS at 1280x1024. Although my copy of MW3 is cracked (Probably mentioning that got my thread locked, but that's a bit unfair.), I still don't expect that vast a difference in framerates. It's not only MW3 that I have problems with, it's also with Battlefield 3, Skyrim, DiRT 3, Borderlands and Just Cause 2 (All of which I own legitimately, so don't say it's all because of cracks etc). I also get TERRIBLE performance in OpenGL games such as Minecraft, Alien Arena, Sauerbraten and RuneScape. Minecraft and RuneScape a re probably the worst affected. RuneScape gets 30FPS normally, then drops to 20FPS when moving the camera. Minecraft gets roughly 40FPS but drops to between 20FPS and 30FPS whenever I start doing something.
The friend with the almost identical rig to me, gets perfect performance with all his games (120+FPS in Minecraft, not checked with RuneScape). He doesn't have Battlefield 3, DiRT 3 or Just Cause 2, but he gets at least 40FPS at his resolution on Skyrim and Borderlands.
I checked nVidia's optimal playable settings for each of my games, and I am supposed to get average 46FPS on Battlefield 3 maxed settings on my resolution, however, I can hardly manage to reach 46FPS at "High" with no AA at 1280x720. At 1280x1024, I still fall 10-30FPS below what my framerates should be according to nVidia's optimal playable settings.
Skyrim in particular seems to have problems too, whenever I go near water, my framerate drops from 30FPS to around 15FPS.
I have no clue as to why this is happening besides the possiblity of a hardware fault.
Here's what I have tried:
Reinstalling drivers (Several times)
Reseating the GPU and power cables
Closing ALL programs that aren't in use.
Running a virus scan (ESET NOD32)
Cleaning the registry and temp folders (CCleaner)
Trying the nVidia beta drivers
Outdated drivers from the ASUS website
IOBit Game Booster
If there's anything else I can try, please let me know.
