I saw the same thing with PAYDAY 2, but I couldn't restore the low perf so I guess they just reworked their engine while they added the SMAA and SSAO thing, so I doubt those patches had anything to do with that :/</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
