I recently bought a EVGA GTX 780 SC with ACX cooling in replacement of my XFX R7790 but i am actually getting worse fps in most games i used to get 60 to 120 fps in bf4 with my old card and now my fps seems maxed at 110 on any setting i get the same fps on low as on ultra.
during fights i get about 30-40 fps and with my old card that would be 70-80 fps.


I am extremely sorry for my bad english (i'm only 16 and don't get english in school that much)

It sounds like there is some sort of bottleneck going on. Getting the same FPS at low and ultra is usually a CPU problem.

With the AMD card in battlefiled 4 you were probably using Mantle (which doesn't work on Nvidia hardware) and gives a big boost to slower CPU.

What are the specs for the rest of you're system?

Did you remove all of your old AMD drivers?

-AMD Phenom II X4 995 3.2 Ghz
-i don't know what ram but 8GB (should be enough)

and mantle does not support my previous card so that wont be the problem

You might want to check if you're chipset drivers are all up to date then (Windows tends to install rather old drivers).

Also the 7790 *is* supported by Mantle as all GCN based cards are supported (so HD 7750 and up). The 7790 doesn't support true audio (even though it should) but it definitely does have mantle support.

You're CPU is a bit slow by modern standards- it might be pulling the maximum speeds down a bit, still those are rather high numbers- I gather you're not playing at a very hight resolution?

i didnt get any option for mantle though and the fps was even worse before i reinstalled and im playing on 1920x1080

I have been playing around with Precision X (because my computer is running pretty loud after 1-2 minutes of unigine valley) and it seems that when i set the fan speed higher or lower it doesn't change, my guess is that the cpu is overheating and that the fan is seet to 100% because of this. The question is can this be the cause of my low fps ?


also my CPU is quad-core but when i unparck my cores it only shows 3.

You should have CORE0 - CORE3 (4 cores total).

An easy way to tell if your CPU is the issue, is load up BF4 single player. Single player is much less cpu intensive, so if you get higher fps in single player that will confirm that you have a CPU bottleneck.

that x4 995 is the problem, it is a huge cpu bottleneck for a 780. you need an intel i5-4430 or an amd fx6300 or higher if you want to be able to keep up with the 780..... preferably an i5-4670k or and amd fx8320.

i installed windows 8 and it goes flawlessly i'm getting 80-120 fps with ultra preset (wich im not gonna use)

the only problem is that my cpu fan is running pretty loud im probably gonna get a new one and then save up for a new mobo and cpu
