The CPU's clock speed is really holding you back. Most games need 3ghz and more. I have a quad core running at 4ghz and some games still get slowdowns.
Maybe enable all the recommended speed hacks and see if that helps but I would say it's definitely the CPU. I'm note sure about the graphics card though, I'm assuming you're using a laptop?

The single threaded performance of the 4510u is just right at the recommended level for non demanding titles. This is assuming that your laptop is as to use 100% of it's CPU performance. So if you want to run a demanding game then it will not work well and if it thermal throttles then even non demanding titles will probably have performance issues.
U series Intel CPUs are not ideal to run high CPU intensive tasks on for long periods of time since they are more designed for burst performance. Boosting up much and high to keep the system responsive then dropping back to the base clock to keep power and heat more manageable in smaller form factors.

Tempratures do effect how much of a boost to the frequencies of the CPU and GPU there is. With more room between the thermal limits set by the manufacturer and the tempratures from the sensors the higher turbo boost for intel will allow the 4510u to get to (up to it's max boost of 3.1 GHz). It is also not the temperature if the laptop as a whole but the temps of the cpu package and all the individual cores that matter for turbo boost.
Aside from temperature limits there are also power draw limits, some manufacturers set these quite a bit lower then the laptop will draw at full load (fully stressing all parts of the laptop that use power) to keep battery life at a good number to have useless stats for marketing. These limits can also be even lower when on battery power and add to the many reasons you should not game, use emulators, or do any other stressful things while not plugged in.

Like TKSilver said, I use emulators like PCSX2 and RPCS3 on my laptop only when plugged in with an external cooler to keep temperature low. I've noticed throttled speed when I'm running it on battery.
