tressfx problem in tomb raider with 7850

[soheil253]

my rig

amd fx 6300 at 4.5ghz
8gb ddr3 ram
amd radeon 7850 1gb


when i play on ultimate settings its around 30 fps which im fine, but everytime i aim the bow or gun or whenever the camera gets close to lauras hair, my fps drops massively to 16-21. this is only when aiming. without tressfx its perferct though :/ i play at 1080p. could this be a sign of vram running out? it doesnt happen at 1600x900 (720p) just at 1920x1080

That's for everyone, tressfx is a very new technology, even experimantal, and it has sh!tload of optimization issues. nothing wrong with ur pc.
i suggest turning it off, you would see a HUGE increase in FPS.

and in case you dont know tressfx= calculation of every piece of hair for a more realistic hair experience, nothing else.

i have 3GB of vram, and that sh!t still drops down my fps by a so much.
