FPS drop in 90% of my games

Specs:
i5-2500K @ 3.30GHz
GTX 770 2GB
8GB RAM
Windows 7 64-bit

I've been fed up with this problem for at least 1 year and yet I still can't figure it out which one is the culprit. Borderlands 2, Far Cry 3, XCOM, Company Of Heroes 2, Tomb Raider, Payday 2, Mafia 2, Batman Arkham City and Origins, Sleeping Dogs, Assassin's Creed 3, Serious Sam 3 BFE, etc.

All of them are amazing games and I don't know whether I should blame those developers for badly optimizing their games or my PC's fault. All obvious methods were applied but sadly they turned out to be futile.

Are there any ex-victims able to help me? Any useful suggestion is appreciated. Thanks in advance.

Check for heat or throttling. What frame rate and settings are you getting/using?

Pardon me for asking a stupid question. How do you check the throttling?

There is another program called throttlewatch? IDK, I don't have a throttling issue. Do a webserch for CPU throttling and see what comes up.

Sorry for the late reply as I got a lot stuff to do in my hands.

Maximum temperature while playing games:
CPU:79C
GPU:85C or above

Oh, the throttlewatch is only available for Pentium and Xeon. Therefore, I can't apply it on my CPU.

CPU issue. 80C is much to high. Either the HSF isn't on all the way, the sink is filled with dust, or the isn't spinning/fast enough.

OK, I have cleaned up my CPU fan but it just makes it worse. Now my CPU temperature has reached up to 90++C! What happened to my CPU?

How old is your processor? Also some of the settings in your games may be stressing the processor like shadows are extremely CPU intensive.

Not more than 3 years.

Are you using the stock fan? What did you"clean up" on the fan? If you removed dust and it got worse I suspect the fan is dying.

Yeah, I'm using the stock fan now and I cleaned up the dust by separating the fan and the heatsink and swept them with paint brush.

Ok, CPU is clearly overheating. Next question is WHY.

Try re-applying thermal past and see if that helps.

But yeah, I basically have the same rig as you (just with a 2600k), so you should be able to max everything under the sun. Clearly looks like a thermal issue.

Just replace the stock fan with an aftermarket one and feel the difference.

You could also look into getting a new heat sink or just a new processor in general. Other than that I don't know what the problem is other than your heat sink and CPU fan and thermal paste may be an issue as well.

Did you take off the CPU fan? seperating it from the CPU and not re-apply thermal paste? If so that's your problem.

Well, I have ordered a new CPU fan. Will report back after setting up the new one.

Phew, got a new CPU fan and now the temperature is around 60++C during gaming but that doesn't mean it completely eliminates the FPS drop issue. In a meantime, I found something peculiar with my CPU. During gaming, the CPU clock speed is strangely inconsistent. All 4 cores fluctuate between 3.3GHz and 1.5GHz.

Any idea what happened to my CPU?

What HSF did you get? With the cores dropping down it sounds like the thermal protection is still kicking in. Double check it's installed correctly.

Sorry to ask but what is HSF?

Heat Sink Fan. It's the thing you just bought.

Should be better then stock. (Some of them aren't.) Make sure the fan isn't stuck at slow speed and that it's installed correctly with the right amount of TIM. (thermal paste.)

Found a fix! I downloaded this mighty program called ThrottleStop and followed instructions from Internet by unticking BD PROCHOT, EIST and C1E and then turn on in order to make it work. Guess what? No more CPU clock speed drop and FPS drop! Although somehow 4 cores will drop down to 3.19xxGhz for unknown reasons, they are not big deal as long as they never drop down to 1.5Ghz that's all.

Temperature is fine. The maximum temperature I get is 69C on 4 cores and sometimes the second core reaches to 72C. Hopefully it's not a huge problem for my CPU.

Tcase, or Intels max temp for that CPU is 72.6C. Your temps are still to close to Tcase for my liking. Turning off the protection for the CPU will fix it, but isn't recommended because now the CPU can't throttle down to save itself. If you are in the northern hemisphere and summer comes with higher ambient temps, you could cross 73C and the CPU might not survive.
