Tera Freeze after tabbing out and in

    Heya guys,


    suddenly my Tera is freezing everytime if I tab out and back in, mostly 3-10secs. In my Task Manager under Processes the TERA.exe*32 shows 00 CPU during the freeze.
    I just got that problem, never happened before....


    I play with full graphics and in "Windows(full screen)"


    Here is a video of it:




    Computer stats:


    Intel Core i7-6700k
    CPU @ 4.00GHz
    16,00GB RAM
    NVIDIA GeForce GTX 970

    Have that too. Tho my lag is about .25 seconds and doesn't really bother me. Reason? I dunno. Started to happen 1 yr ago and still persists :D
