So i just got the ROG G750 JW and gforce experience sets the setting on very high for every thing on my laptop (for lol)

so when its plugged in i get 200 fps ( not sure if true :rolleyes: ) with not even a stutter,
but when its plugged out i get 30-50ish fps and it lags (on battery).

Any idea why, please help.

You cannot game properly on battery, the G750's dedicated card doesn't allow it.. not smoothly.

is there any way to fix that or bypass that ?
also is it in this model or every other model ?
further more i was playing dmc4 and got 15~~ fps on battery... that is just sad..
thanks...

Not that I'm aware of, but if you did, the battery would only last around 40 minutes to 50 and would strain it severely.

The GPU is dedicated, not integrated. It has it's own components and everything it needs that a GPU would normally, thus requires a lot of power.

If you look at your charging brick, you'll find that it supplies 20volts and 10amps, I have a good feeling a lot of that power from the brick goes to the GPU directly. (Theoretically anyway).

With the first generation G750's, the internal graphics (Inside the 4700) is completely ignored. If you wanted that, (which probably wouldn't run the games anyway) you would have needed to buy the second gen or above, being the G750JM / JS / JZ

You need to go to the NVidia GeForce Experience, search for Battery Boost and set it properly/disable it. Your choice.
P.S. I see that ROG Guru here are pretty disinformed, what a shame...

lower the graphics to low-medium, then you can play on battery.... gives you 1.5 hours (2 games)

above answer is for your LoL question. I don't know other games... but with lower graphics, you decrease the power consumption and the battery can power both CPU and GPU

Again? BatteryBoost is set to target 30fps with battery on so to drop out further consumptions. Disabiling BatteryBoost will give full power to GPU but will drain more battery charge.

Check your G750JW bios version to see if you are running version 208 and the thread below if you haven't already to consider trying a bios update which may help some.
If you 'stress' your system while monitoring the CPU speed on battery power, it should also give you a better idea if a bios update may help.
Please be aware there is the possibility of killing your system if something goes wrong with the bios update if you would rather not take this chance, but normally you should not have any problems doing this.

so aggressive... you are what's wrong with the world. There are no Gurus here, just people that have experiences and try to help. The Guru labeling is given by ASUS and it's based on number of posts. Plus, it is evident you have no formal education on engineering, based on your statements (not worth discussing further with you).
Be nice, or get out.

silvershadow0099, it depends on the game, and it will run games better than an Optimus using an Intel GPU, but you need to set up profiles in your games for running on battery - set everything way down to start to get FPS up, and then tune up as best gives you a good gaming experience - some games that won't be possible on battery.

High end gaming GPU's require a lot of power :)

If you want to get the best performance, uninstall Asus Power4Gear, and make a High Performance Power plan for battery use - set brightness down, set CPU Performance to Min/Max 0%/99% to disable CPU Turbo - fixes it to 2.4ghz - enough for the GPU on battery, and then tune the game for battery use.

Please come back and let us know how it works out, and if you have any more questions specific to the game.

silvershadow0099, sorry, but it is a problem for all high end laptops. You need an external power source the same as the AC adapter will provide, build one of those and go into business selling them.

It isn't as bad as you think though. With the 980m/970m drawing much less power, and Nvidia's FPS cap (variable?) set at 30 FPS, you can extend battery life a tad longer, and still get some good game play in.

Check out this video on the subject. From ==> http://rog.asus.com/forum/showthread.php?54387-New-member-and-have-some-questions-about-buying-laptop&p=455306&viewfull=1#post455306

Cutting down eye candy, resolution, fps, all go toward extending the battery time.

If you want to go the other direction, keeping FPS up with all the goodies, then find an external power supply to plug into the laptop that is portable and easy to move around. When you find one or make one, please post back here - we want one too :)

GeForce experience Battery Boost target FPS can be changed anywhere between 30-60FPS.
