[SOLVED] I'm not hitting the fps that i thought i would

[Marte3356]

At the start here is my PC specs:
CPU: I5-4460 3.20 ghz
Motherboard: H81M-P33
RAM: 8gb ddr3 800mhz frequency (dont know the brand)
GPU: XFX Radeon RX 580 8gb
PSU : 600w (dont know the brand eather)

Problem is that i upgraded my gpu from Gygabite 750 ti to Rx 580 and i am not getting high consistent frame rate that i should.
I did clean windows install after installing the gpu. For example in CSGO with 750 ti at lowest settings i was getting around 120-140 fps but it was consistent with RX 580 i am getting a little bit higher frame rates like around 150fps but in more open areas it drops to 70-90. Same problem in League of legends in big fights fps drops down alot. I did not overclock my GPU or CPU.
Bigger games like Apex legends or GTA V starts stuttering my whole PC i just cant move the mouse. So i want to hear you people opinions (sorry for the mistakes)

The problem isn't the RX580, but the PC its connected to. That's a 4 core CPU and slow DDR3 RAM(probably a single module running in single channel mode). Also, based on your current specs I'd hazard a guess that the "600 watt PSU" is probably a 5 year old lower end unit. The RX580 is a power hungry GPU and requires a quality PSU.

Did you at least remove the old drivers before installing the 580?

OK so i said i did a clean Windows install so that means yes i did remove drivers. My ram are dual channel and my PSU is brand new Akyga AK-P3-600

Akyga AK-P3-600

That is not a 600W PSU. Not really. In modern systems the rail that matters the most is the 12V and your PSU can output 468W at peak on the 12V rail. It's a questionable quality and unknown reliability PSU that should not have been used in a gaming rig.
PSU is the heart and blood of your system. If you cheap out on it, guess what will happen.

So you guys are telling me that if i change my psu the problem should be solved or I still need better ram ?

 

[dotas1]

We can not know because we are not there to see if you are missing something. PSU should be changed even if it's not the cause of the problem. For RAM you can not do much as it's DDR3 so not many options there. BTW, it's not 800 MHz that you have, it's 1600 because it's doubled (Double Data Rate)

I did miss the part about a clean Windows install.

What is your CPU and GPU usage while gaming?

CPU stays at 90-97% while GPU sits on 50-70%

There you go. CPU is at max usage.

Any solutions? CPU upgrade ?

 

[dotas1]

Yeah that's cpu bottleneck. How are your temps? Idle and while gaming for cpu and gpu please

Full upgrade. Motherboard, CPU and RAM.
