Is the performance difference mostly noticeable on fishbowl?

Attachment: about:support when running with nvidia card

firefox 36
intel hd 4600
omtc off   100 fish  ~60fps
omtc on    100 fish  ~41fps
nvidia GT 740M
omtc off   100 fish  ~43fps
omtc on     10 fish  ~2fps
omtc on    100 fish  ~2fps
omtc on   1000 fish  ~2fps

notice in attached file:
GPU #2 Active: false
WebGL Renderer: Google Inc. -- ANGLE (Intel(R) HD Graphics 4600 
But firefox is running under the nvidia card(confirmed with "nvidia gpu activity")

Attachment: 37.0b_gt740m

firefox 37.0beta
intel hd 4600
omtc off   100 fish  ~60fps (fish tank is red, no water refractions)
omtc on    100 fish  ~56fps
nvidia GT 740M
omtc off   100 fish  ~43fps (fish tank is red, no water refractions)
omtc on    100 fish  ~60fps
omtc on    500 fish  ~20fps

again notice in attached file:
GPU #2 Active: false
WebGL Renderer: Google Inc. -- ANGLE (NVIDIA GeForce GT 740M Direct3D11 vs_5_0 ps_5_0)
This time the webgl renderer is set correctly, but why "gpu #2 active" still false?

omtc off   100 fish  ~60fps (fish tank is red, no water refractions)
omtc on    100 fish  ~56fps
nvidia GT 740M
omtc off   100 fish  ~60fps (fish tank is red, no water refractions)
omtc on    100 fish  ~60fps
omtc on    500 fish  ~20fps

also had a crash while running the demo with omtc off :/

These results suggest that 37 fixes the issue you we're seeing. Correct?
