Am I having CPU bottleneck?

blackstarempire · Aug 16, 2014

I read an article in internet, said that if you lower the game setting but not having fps increase then you have CPU bottleneck, then I try it out and I don't have any fps increase just like the article said even I set it to maximum fps it still the same. After that I notice something too, I get lag and stuttering only while the screen rendering particle, plantation, or too many people. Other than that scene the game is smooth and playable (this happen to me almost in every game I test) so my question is:

1. Is the article speak the truth?
2. If I really having CPU bottleneck, what is the temporary solution before I buy a new CPU?

as an addition, I'm using Core 2 Quad Q8400 and HD 7790. I'm playing games in 1366x768 resolution

you may the lag and shuttering also be a reason for insufficient or faulty power supply corrupted or backdated drivers virus or malware and not enough ram....

that cpu is definatly a bottleneck. The res is low however i dont think it should be to much of a problem. you could overclock it to get extra power.

Sounds like something I might have posted.
Do you have a link?

Your cpu is several generations old and a quad.
Most games depend on one or two fast cores for performance so I think your upgrade is to a more modern cpu with faster cores.

The 7790 is not exactly a fast gaming card either so a real upgrade might well include both cpu and gpu.

As a temporary solution, have you tried overclocking your Q8400?

definatly the 7790 is not the strongest but it probably is the cpu.

geofelt :

I don't know how to overclock a CPU, can you tell me about it? I'm using American Megatrends BIOS

blackstarempire :

you need to get into the bios. You will see something called clock speed. change that little by little like from 2.6 to 2.7 and then download prime95 and stress test it for(30 min at minnimum) and if it works try it again if it doesnt add more voltage.
