    Hi for some reason lately ive noticed im getting shocking fps on Garry's Mod. A week ago i was getting fine fps and i sorta lag on all games now.

    Ive tried reformatting turning off vsync etc etc.

    Here a copy of the gpu usage ingame.


    For some reason its not using the full gpu power ingame and which is causing me to get really shocking unplayable fps. A week ago iwas getting perfectly fine fps on here. Ive tried reinstalling games aswell.

    Also tried latest drivers and made no difference.

    Any ideas?

    I think something is choking your CPU and it is not delivering to the GPU. Have a look at the CPU to see if it's usage is at 100%, and if it is, look for what program is causing this.

    i don't spose the card is reverting back to 2d mode which would kill performance?

    there is a setting in the nvidia control panel, manage 3d settings, power management mode, change to prefer maximum performance instead of adaptive or power saving

    see how you get on
