    Hi all,

    So I have recently upgraded my CPU from 17-3630qm to an i7-3940xm and GPU from GTX675m to GTX980m. The laptop had been running fine no problems. The GTX675m video card wasn't really very good and needed upgrading.

    So I upgraded to the GTX980m and flashed the BIOS to the unlocked A11. Ever since the upgrade however, the graphics looks great in game but I am getting awful screen tearing issues, happens when the in game character is running around. Doesn't happen if I stand still in-game.

    I have tried altering SO many different settings. It mostly happens in Fortnite where it renders the game almost unplayable. I have disabled and enabled V-Sync, lowered 3D Resolution to the lowest setting and i still get screen tearing even on the lowest graphical settings.

    Does anyone know what the best settings are for the GTX980m or if anyone knows why I might be getting god awful screen tearing, any help would be greatly appreciated. The 980m has more than enough power to play Fortnite and other games without experiencing this.

    Please help!

    Many Thanks

    MUSTANG

    Hey there

    What is it like in benchmarks, all running fine and performance is as expected?

    How about other games, any tearing there? Or is it just Fortnite?

    I used Valley Benchmark 1.0 yesterday and there was an intermittent stutter but no screen tearing.

    The screen tearing happens constantly on Fortnite I've managed to get it to a minumum with everything on low and V-Sync On, but it hasn't eradictaed it completely, its just playable. Apex Legends plays better than fortnite but still has screen tearing.

    I just benchmarked with Novabench and the results are below. Pretty poor! novabench.JPG

    That's weird, have you tried using an app like HWInfo64 to see if the GPU is throttling? I would suggest running 3d Mark and comparing your score to a similar set up. That's the easiest way I found of telling when my 1070 is throttling. If I get 5.1k score in Time Spy means it's fine, if I get 2.6k then it's throttling and I have to do Mr.Fox's sleep / wake trick to get it back up to scratch.

    You will also see if Performance Limits are triggered there and for what reason, along with max GPU power draw etc. all useful things to see if you're throttling.

    I also use RTSS along with HWInfo64 so can see stats in 3d Mark in real-time, like temps, fan speed, fps, etc. so I just let 3d mark run the test for a moments and then I know what the deal is quite quickly.

    Run something like 3dmark11 or 3dmark firestrike.

    For the tearing, did you try turning on v-sync?

    What power adapter are you running?

    It kinda looks like both CPU and GPU are power starved.

    I did a couple of benchmarks. The first one is the Sky Diver test, the second is the Time Spy test.

    I did have V-Sync turned on.

    My power adapter is pictured below, how would i know if they are power starved? The battery doesn't last very long unless it is plugged in, do you think that might be an issue?

    Just run the pure Fire Strike non Extreme test. That's most comparable in your GPU performance range. A 980m should do something ~10-11k graphics points there.

    675m and 980m both are 100w cards, so the 240w power adapter should be sufficient, but yours may have become "old" and is not delivering enough power anymore.

    Fire Strike results below

    After installing the 980m I read somewhere that i may have to switch from legacy bios mode to uefi mode, is this true, if so how?

    Did you remove your old GPU drivers with DDU?

    Its scoring low, both on the CPU and on the GPU side, mainly on the GPU side.
