Bought a New Gpu not using it's full power

[Devin_]

Well, I've been playing Witcher 3 on my PC and was running like 40-55 fps on lowest settings so I decided to go from the GTX 750ti I owned to the GTX 770 SSC ACX 2.0 from NVIDIA but I was sill getting massive performance dips and fps drops and I don't know why.

PC Specs:
AMD A10 6700k APU Quad-Core
NVIDIA GTX 770 4GB ACX 2.0 EVGA
8 GB Ram (7.19 GB Usable)
MS-7778 Ver 1:0 Motherboard
Photon-750 750W PSU

Your CPU is likely bottlenecking a lot.

 

[Devin_]

Ok why do you say that?

 

[turkey3_scratch]

Because it's an old processor and does not have much power. A better GPU always uses a lot more CPU resources. You should overclock it.

I don't exactly know how to overclock it other then AMD Overdrive the application that comes with most amd processors

 

[turkey3_scratch]

Rather than speculate, monitor your CPU and GPU usage with a program like MSI afterburner. The Athlon can struggle on games which require hefty single core performance.

I've done that and I notice whenever i play any game its always at 100% usage on the cpu and then itll dip down but there is not thermal throttling

 

[turkey3_scratch]

Yeah, if it is at 100% CPU usage on any core that could definitely be a factor for the lesser graphics performance unfortunately.

In amd overdrive i see these core multiplier and pci speed etc. stuff would you know how to overclock that stuff or cause i need some serious help with this because i hate not being able to play these games

 

[turkey3_scratch]

I'm not experienced in overclocking, I recommend you simply Google overclocking your CPU.

 

[ToxicFantom]

Your CPU is limiting your performance. With that CPU you will always get dips to 40fps. Changing to a GTX 770 will not increase the minimum framerate. It will only increase the graphical settings that you can maintain at that framrate.

ToxicFantom, in the withcer 3 i do get to 60 fps with no problem but there is always dipping but when i increase or decrease it just gets worse
