I have Zotac1070ti 8gb
Im not sure why.But my fps when im playing a game called pubg is not stable.
Some of my friends have `1070ti but different brands have atleast 160 pfs to 130 pfs.....Mine starts at 175 then drops at 80 when i land and it rarely goes up to a 100 fps..

This is my pc specs.
I7-4790K
msi h97 gaming 3-MBoard
16GB RAM-1600 DDR3
240 GB SSD

Please help.
