(I was told to ask this here after posting it on reddit. Please help!)
I bought my computer 3-4 months ago, and have since upgraded my GPU which threw my whole world upside down.
I first started noticing this after I replaced my 6950 with a 7990 – during which the new PSU I bought was faulty and fried my mobo and I had to RMA it. After I replaced my mobo everything seemed to be running great with the new GPU, but in some games my CPU was bottlenecking(details on fps below.) I attributed this to my GPU outpacing my CPU so much, as I was used to my 6950 holding back my fps while my CPU was barely trying but comparing with my friend’s comp I feel something is wrong. On more demanding games my CPU is stopping me from getting FPS comparable to what benchmarks for the 7990 are claiming(its maxing out) – and those benchmarks are using an older non OCed CPU.
I’ll use BF4 as my primary example, as I’ve been playing it the most recently and I can compare with my friend who also has it. In BF4 on ultra w/o AA I get a minimum of about 35 fps at absolute worst times, but strangely I get an excess of 130 fps when in less demanding areas. I’ve had to disable windows aero to get it to run that well (with it I was getting 5-10 less fps.) Turning down the graphics to low doesn’t make that much of a difference, and sometimes I get worse fps on low… Now I wouldn’t complain much about the fps I’m getting as they aren’t horrible, but the game also takes AGES to load, sometimes 2 minutes!
I’d just chalk all these issues up to bf4 being a piece of shit, but my cause from concern comes from the fact that my friend who has the exact same computer as me (except a 660ti instead of a 7990) gets HIGHER fps AND 15-20 second load times! Something has to be wrong on my end and I’m not sure what. When I run bf4 all my CPU cores are pegged at 95-100% while my GPU is around 60%. During this my friend says his are at 70-85% max (again, he has the same CPU.)
When I play Crysis 3, I get the same problem: 10-15 lower fps than benchmarks while my CPU is pegged and my GPU is not. It doesn’t make sense to me that my new CPU is bottlenecking me so… why is my CPU running so much worse than my friends?
I’ve got an i5 4670k (not OCed), a 7990 (with SLI on), a 7200 rpm HD, 8g of ram, and I am using 2 monitors (1280 x 1024 and 1080p.) Nothing is overheating, temps are <55c for CPU and <70c for GPU. I’ve tried unparking my cores – didn’t change anything and my friend never did that either yet his still runs better.
I've since tested w/o crossfire enabled in BF4, and got almost the exact same FPS. The only difference was that instead of my CPU maxed and my GPU at about 70%, the usages switched! My CPU was running at about 80% and my GPU ~95, almost the same as what my friend experiences. What gives? How can I test what exactly is causing this?
