You have Windows, right? Try out setting different dxlevels (-dxlevel 98, 95, 90, 100) too see how it affects your FPS.
Adding these launch options should help a bit:
-freq 120 : sets the game's refresh rate to 120HZ for your monitor
-threads 4 : increases the number of worker threads available (according to your 7700HQ CPU, this is the ideal value)
And then you can test out these:
-r_emulate_gl
-high
-nouserclip
