    [Solved]Problems with nVIDIA Geforce 820M

    Hi,

    I bought an ASUS laptop recently, with the following conf:

    Core i5 4210U
    6GB RAM DDR3 1600MHz
    HDD 750GB 7200rpm
    nVIDIA Geforce 820M 1GB
    Windows 8.1 x64

    My problem is, i know the videocard isn't very good, but it is capable to run games like Dirt 3, Need For Speed Hot Pursuit and CS: GO, right? So, why i have normally 50~60fps ingame but there are times that it feels like the game are running in slow motion during 2 or 3 seconds, but after that the game continues to run well? The temperatures are OK (under 60 degrees in all components), the drivers are the more recent (340.52), ingame settings are optimized (it occurs even if i choose low graphics quality), and the CPU is supposed to handle not-so-demanding games, like the ones i refered. Hell, even with the Football Manager 2014 3D engine i have this problem!

    Can someone help? I will appreciate :)

    That's a pretty lowend card but it should be able to run those on low. Maybe the laptop isn't switching over to the Nvidia card and keeps using the Intel one?

    Hi nhlkoho, thanks for the answer.

    The games are using the nVidia card, and they run pretty well (Dirt3 runs at 50fps, 1366x768 Medium-High), but occasionally i experience a slow motion time, which make the games unplayable, even the less demanding ones.

    You can try throwing an SSD in there, but other than that you're not going to increase performance with demanding games. That i5 is a dual core variant and it's a slow one. The 820m isn't really a gaming chip either.

    It almost sounds like it's running out of vram every now and then..if it's a variable graphics card for the vram, you could try and increase it

    What you want to do is make sure you are running on a High Performance profile and that if there is an ASUS utility to control power usage, fan speed profiles, or something related to speed, make sure its set up for performance. On my Vaio with a i7-4500U, the power profile as well as a fan profile setting in Sony's control panel, will dictate whether or not it can go over the 15W TDP to ~22W. What happens is if you hit the 15W TDP, the CPU and iGPU will massively underclock momentarily. You aren't using the iGPU so I'm assuming its strictly a CPU downclock going on if your GPU isn't overheating, are you sure you are monitoring LOAD temperatures? Because ~60C is very low on laptops under load unless you have a relatively large model or live in somewhere very cold.

    Thank you all.

    snip3r_3, Dirt3 running windowed with SpeedFan on the left, thats how i measure temps eheh. When i was running the ingame benchmark i hited 64ºC, but nothing further. The lapton is good, nice airflow, 15,4", the only problem is the videocard. But hey, with 600 euro i couldn't buy anything more powerfull...

    I will try some of your advices (except the SSD one, isn't an HDD with 7200rpm and 16MB cache powerfull enough?), thank you all again.

    Hi again,

    I just tried your recommendations, nothing worked...

    Meanwhile i tried something new: Dirt3 on the laptop screen, GPU-Z on another screen. Clocks started like this:
    GPU Core Clock: 162MHz
    GPU Memory Clock: 405MHz
    GPU Shader Clock: 324MHz
    GPU Temp: 44ºC
    Memory Usage (Dedicated): 0MB
    Memory Usage (Dynamic): 0MB

    Then i started to run the benchmark, and the GPU Core jumped to 954MHz, Memory to 900MHz and Shader to 1,25GHz, BUT here is the thing: when those slow motion moment occurs, the GPU was at 750MHz and even at 162MHz! Another thing that i saw is the amount of Dedicated memory used never leaved the 0MB mark, and the memory usage (dynamic) jumped to 362MB (max value). Checked again the card temp, never goes up to 64º degrees. GPU Load hited 99% one or two times.

    Tried another drivers, same issue. Asus Power4Gear does not work out my problem too. Maybe those GPU low values are the problem? What is even more strange is the FPS showed in benchmark: The game says that the average FPS was 71fps, and the minimum FPS registered was 42! (Im trying now with less demanding settings).

    EDIT: Solved, the solution is so simple that i am ashamed to post it: it has to do with an option in nVidia Control Panel, The energy management mode. Set it to maximum performance and voilá, problem solved. Now, when i am benchmarking Dirt3 the GPU clock always stays at 954MHz, even when the GPU load drops to values like 20% or 30%.

    Thank you, you can block the topic please.
