Unstable fps while gaming

[H471Q]

Hi all, non-native English speaker here. I just bought an Asus A456U with i5-6200U, geforce 930MX, 8GB DDR4 ram, win 10 64-bit. The problem is, whenever I game(Dota 2, GTA V, AC:Syndicate) the fps often spikes like only 10fps for about 5secs and back to 90++ fps. Just a few moment later and the fps reduced to 10 for like 5secs and back to 90++. This happens to often. Anyone knows the cause of this or probably solutions? Thanks !

For Dota 2 this should not happen assuming you are playing at the recommended settings. As for the other 2 games, the gpu is not designed for them as it is a low end card.

What is the temps while you are playing these games?

Thanks for the reply !
I used msi afterburner and the temp range from 45 to 60'C while gaming. I can run gta5 and syndicate at 60fps max with low-medium setting. Still searching for the solution...


I forgot to mention that this problem only occur when I play games on battery, but smooth as butter when plugged in. I've look up the 'power option' setting in control panel. I have the same setting for both battery and plugged-in option and yet the problem still occur.

thanks in advance !

Thinking this may apply (but not sure):

Running a high-performance GPU at full speed while on battery can damage the battery or require more power than the battery can safely supply

High-performance mobile GPUs can require significant amounts of power to operate at full speed. The GTX 765M requires 75 W, while top-of-the-line mobile GPUs like the GTX 780M and GTX 980M can consume up to 122 W.
The GPU is not the only power-hungry part in a laptop. A modern Intel performance mobile CPU typically draws about 47 W at full power. In addition, you need to power other system components, such as the display, disk, and USB peripherals. When you add it all up, you might need anywhere from 140 W to 200 W to operate a gaming laptop under full load depending on your system configuration.
A typical battery in a gaming laptop can store about 60-80 Wh of energy. Most Li-ion batteries are not designed to be discharged faster than twice their Wh rating per hour (2C). In addition, sustained discharge at rates exceeding 1C can significantly reduce the overall service life of the battery. Continuously pulling 150 W or more from a typical 77 Wh battery is not a great idea and your battery could overheat and fail or even catch fire. While it's likely the battery's own protection circuitry would shut down the battery if overloaded or overheated, a device should never subject its battery to an unsafe load at any time during operation.
To avoid overloading the battery, the GPU will typically throttle to a lower clock speed. The GTX 780M on my personal laptop will not run faster than about 400 Mhz when on battery. Lower clock speeds reduce power consumption not only by having transistors switch less rapidly, but also by allowing lower core voltages—power consumption and heat dissipation scale with the square of voltage.

Then it is most likely that the laptop is throttling its performance when it is on battery. This is done to save battery life. My best suggestion is to play while plugged in and do normal things when unplugged.
