Games Lag on Powerful PC

[linex12]

That's my PC:
OS: MS Windows 8.1 64bit
CPU: AMD Athlon x4 750k
GPU: GIGABYTE nVidia Geforce GTX 750 OC 2Gb, 128bit
RAM: 4Gb
HDD: WD Blue 1Tb,7200rpm, 64Mb

The problem is that Prototype and Need for Speed: Undercover don't run smooth when I set the graphics on MAX
I think that my PC is powerful enough to run these games smoothly even they are maxed.
I must say that Need for Speed Most Wanted (2012)
doesn't lag at all.

Your PC is a fine budget machine, and should be able to handle those games. I'd suggest an upgrade to 8gb ram

Yeah but I as I mentioned Need for Speed Most Wanted (2012) ( I mean when it's at max settings) doesn't lag at all, so then why I've troubles with older games? Could it be because of the OS? It's new but the games're old.

I don't think windows 8 is to blame. You can use monitoring software (like MSI afterburner and HWinfo64) to try and find out what's causing the lag

If your CPU usage is high (above 75%) when it lags, it could be the CPU
If your ram usage is high (above 3.7gb) when it lags, you need more ram
If your CPU usage is high (99%) or Vram is high (2048mb) then it's your GPU

when I set the graphics on MAX

Does this mean that you've enabled AA, Physx and other advanced graphical options? What resolution are you playing at? Your GPU is only mid-range and not designed for very high resolutions or advanced graphical options.

Well, yes, everything is on MAX. And also I set resolution to the highest possible. I know what you mean. I'm gonna decrease the graphics a bit.
