you open the bottlecap and look closely at the neck ? NO ?
well we cant really say anything unless u give more details lol

> Unless every single component in the PC works at equal speed, they are all bottlenecks.
> If you were a science student and paid attention in Chemistry class, then while studying 'chemical kinematics' you must have hears the term 'rate-determining step' or simply RDS.
> In a system consisting of multiple components, the whole system's speed is dependent on the slowest component.
> Suppose you are crossing the road along with a small 3 year old boy. You can't run at your normal speed and will have to adjust your speed according to the child's speed. thus, the child (the slowest component in the system) would be the RDS or simple the the speed of the whole system.
> Suppose you command your PC to open up a video:
> the CPU searches the file on the HDD, HDD is super slow: Bottleneck 1.
> the CPU finds the file and loads it into memory. Memory is running at 1333MHz at single channel: bottleneck 2.
> file is loaded into memory, OS loads up the video and audio codec, bottleneck 1 comes into action.
> video codes uses hardware acceleration, calls up the gpu to do stuff.
> GPU copies data from ram,bottleneck 2 comes into play. Data is being copied from system tam to gPU's ram, pcie bus not running at full speed: bottleneck 3.
> GPU is ready to perform stuff, does the stuff, copies data back to system memory, bottleneck 3 comes into play.
> you see... every single component in a system is a bottleneck and you can't really remove it without upgrading your hardware.
Keep the language to English and use decent words.

i understand what bottleneck is ,have also studied chemical kinetics better than anyone...........i want to ask is there any software which helps me to find bottleneck

using fraps:
Run your games, but lower your resolution and eye candy.
If your FPS increases, it indicates that your cpu is strong enough to drive a better graphics configuration.
If your FPS stays the same, you are likely cpu limited.
If your FPS drops significantly, it is an indicator that your cpu is the limiting factor, and a cpu upgrade is in order.

This is impossible, how can FPS decrease while lowering resolution ?

here is answer for you
read - CPU Bottleneck - What is it, and how it affects your games.

If your CPU is older or weaker than the above mentioned CPUs, then test the game at an extremely low resolution. If your framerates improve, then CPU bottleneck is not your issue. If framerates stay the same, then CPU bottleneck could be your issue.
See it is written framerates remain the same, not decrease

Simply run windows task manager and GPU-Z in the background while playing Crysis 2. After playing make sure to check the record for the past few minutes. If CPU utilization is 100% (or close to it) its a CPU bottleneck, if GPU usage is at 100%, then the GPU is a bottleneck, otherwise most likely its the memory. My bet's on the CPU

if the gpu usage is 100%then i think gpu is performing with whole potential ...am i right or am i right?
