Huge FPS drop on G751JT

Icemixxy
Level 7
Hello everyone,

I have owned this G751JT for over a year now without any problems.
I play World of Warcraft 99% of the time, on ultra settings at 55-60 FPS with V-SYNC on.
Today when I logged on, it was fine for 10 minutes, after which my FPS suddenly dropped to about 15. I checked if Windows was updating itself, or AV running in the background and nothing. I did what anyone would, restarted the game. I had 15 FPS from the start. After that I tried restarting the laptop. It worked for 5 minutes, then again the huge drop. Tried resetting the game settings, didn't help.
I haven't installed anything in days, so I thought Nvidia drivers might have became corrupted and tried reinstalling the drivers with clean installation ticked.
Worked fine for 5-10 minutes, but it dropped again. Blew the vents with compressed air, checked temps, they were at 70-75 or so. I didn't check if that was high or not, but the fans weren't blowing out much. I checked rog forums, installed NoteBook FanControl, used the zenbook profile as suggested here and set all vents to 100%.

So at this moment I have wow open, on ultra at 12-16 fps, CPU temp at 58-61 C, GPU 48 C, PCH diode 67 C.

So it's not overheating and now my only guess is Windows has turned upside down. It's W10 x64 home by the way.
I'm somewhat afraid of sending it back in warranty, because the company I bought it from works with an asus authorized service, so I'm a bit untrustful.
My only safe option is try a Windows reinstallation.

Hoping someone has an idea that could help or experienced something similar.

Thank you

ThrottleStop 8.10

Ever heard of ThrottleStop? Turn the Log File option on so you have a record of your CPU's performance while gaming. Usually unchecking BD PROCHOT and checking Set Multiplier and setting that to the maximum value can help out.

Also remember to click on the Turn On button. Post a screenshot if you need further help.

I would recommend updating or downgrading the video driver to 365.10 or 362.00. Some drivers between or before are unstable on some systems. Throttlestop is not needed on non-overheating laptops in my opinion.

I already have 365.10. Even tried a clean install.

Regarding the log: unchecked BD PROCHOT, left everything else the way they were. Did not check set multiplier.

Try the 362.00 driver, create profile for WoW, force it to run on the dedicated video card and set the profile to prefer max performance in power management. Also check with msi afterburner osd what gpu usage and clocks you are having in game Let me know how it goes.

The CPU looks fine. It appears to be running at the proper speed with no signs of throttling.

During that log, were your FPS low? If your game was plodding along then it is time to log the GPU performance. See what speed it is running at while gaming.

Edit :



At 00:56:07 there is some CPU throttling but I am not sure what you were doing at that moment.
The multiplier briefly drops down to 25 which looks like Turbo Boost was disabled. While gaming, the multi should never drop like this.

yes it was low, but only in the last 2 minutes or even ess. when i started logging.
at the start of the log, fps was normal and i had to wait a few minutes for it to drop, but forgot to turn logging off and on.
i did play with the multiplier for a few moments.just decresead it a bit to seethe freq. wow was not running then.

will come back with afterburner results

it's brief because i just started msi afterburner and launched wow.it was 15 fps immediately, because as i've said, fps is good, for a few minutes after restart.no idea why

UPDATE: restarted laptop, and did another test run with msi.
at first the fps was fine, and i wasn't paying attention at the exact moment, but I think it shows where the fps drop happened. the gpu went to 100% instantly.

My logic tells me, that if it's hardware related, it either works or it doesn't, but since a windows restart fixes it for a few minutes, I'm leaning more and more towards a windows reinstall and if that doesn't fix it, i'll have to send it back.that means 3-4 weeks without the laptop.

I will just post a small update:
-reinstalled windows and now I have been playing for 3 hours without any issues. so far it seems that it was windows' fault
