Quad-buffer OpenGL for 4.2 core-profile? -


i'm developing 3d stereoscopic opengl app windows 7 , nvidia quadro k5000 cards. rendering scene left , right-eye perspectives using gldrawbuffer(gl_back_left) , gldrawbuffer(gl_back_right) works fine, , 3d effect displayed nicely.

while works, i'd use nvidia's nsight graphics local debugging. however, error "cannot enter frame debugging. nsight supports frame debugging ... opengl 4.2. reason: gldrawbuffer(bufs[i] = 0x00000402)"

if calls gldrawbuffer removed, nsight local debugging works.

going through opengl 4.2 spec, drawbuffer described in section 4.2.1

so, 2 questions:

1) there other way (besides drawbuffer) specify back_right or back_left buffers drawing quad-buffers?

2) nsight capable of doing frame-level debugging on quad-buffered stereoscopic setups? if so, how?
