cod 4 at my laptop... (fps drop)

Try checking the temps of your components,
You can use Speccy which is a reliable app which tells you usage/temp for each component.
Here's a download link: Speccy - System Information - Free Download
Reason for checking your temps is because your CPU may be thermal throttling when under load (playing games)

Another thing which I can think of is maybe try reinstalling/making sure your drivers are up to date.
I'm not 100% sure these solutions will have any effect as I don't personally own a laptop myself to game on,
but hopefully your issues are resolved soon!

Could also be some kind of ram issue.
If you open taskmanager you can see how much physical memory that are used in %.

You could try using Razer game booster there are functions like cleaning ram, closes programs that are not neccessary while gaming and so on.

If ram is the issue, you should download memtestx86 and run the test, if physically damaged you should replace them with new ones, if you have high memory usage but the memtest dont give you any errors its probably a program running in the background that causes it.

If temparatures is the problem, the game booster wont help at all, then you should clean out all the dust you can find. Do not do that with a vacuum-cleaner, that might destroy your computer. Best thing to use is air on can ( dunno if thats the right name )

Hey man. Are you using windows 10? I have had issues with a memory leak from something in win10. If not, all the suggestions above should sort you out

I also think that it's a heat problem.

As deleted User already said, some cpu's reduce their power to avoid getting too warm.
On normal pc's you could check the bios for such settings and disable it, but laptops often have a reduced bios so you can't edit much there

@Hoopik
What about GPU temps? What CPU and GPU do u have in your laptop? Different models works on different temps, so it's kinda important to know first what hardware do you have.

EDIT: U can download HWMonitor and post screenshot here - it will show temps and all needed informations.

Upgraded any parts lately?

@Jack
I would be fairly surprised if he did (it's a laptop).

@Hoopik Download HwMonitor and give us a screenshot under load (when u're playing and fps drops) like have already said myst. Also, under load give us a screenshot from main tab of CPU-Z.

Operative temperature for this cpu is 105 degrees. Throttling can be activated earlier ofc, but still - 74 degrees is in normal border temperature under load. Even for normal PCs

But we've to w8 for screenshots

Edit: And no offense to hawkie, but don't use any kind of game boosters. U can do it by yourself to clean your os, without external stuff like this.

@Hoopik the values look fine..

Programs are "downloading" temperature of the gpu from driver. If programs can't display temperature = maybe sth is wrong with a driver (or with a sensor on gpu).

PPM on desktop > AMD Catalyst Control Center > Performance > AMD Overdrive > Enable AMD Overdrive. Then u should see two new options in Performance tab - CPU OverDrive and Graphics Overdrive. Try look for temperature here.

Also, from your ss we can see, that cpu is dumping timings, but it's cuz of energy saving (during idle). I'm talking about min value (timings) ofc. Current value, that is 2 GHz is proly because u minimized game = cpu usage was lower = cpu is automatically changing tmings to lower (energy saving). Turbo Boost (max value of timings) is working fine, temperatures are okey. Observe timing frequency under load, but use tab in-game (How to: CPU and GPU usage along with FPS in-game). When u'll see the drop of FPS, u'll check rapidly how are looking your cores clocks. If there will be change from for example 2,6 GHz (your base clock) to lower value we can say, that it's throttling issue.

Try remove it completly from safe mode (usng Revo Unninstaller for exaple). And then install it again (in safe mode ofc). Do it the same with AMD driver.

Btw. u don't need to install overdrive I guess. If u have AMD driver for your gpu that feature is included in it
