poly_mode 1 1 fps slowdown

Hi all...

since sometime ago im having fps slowdown when use poly_mode 1 1 on geometry's.

i post a patch that drops from 60fps to 15fps with poly_mode is set to 1 1 if i push the mesh to posZ -7. i get again 60fps.

this happens in fullscreen at 1920x1080

happen this to everybody? is this normal?

im on macbook pro 15" retina and max 6.1.3

Max Patch
Copy patch and select New From Clipboard in Max.

thanks!

happens to me too, seems normal since poly_mode 1 means a lot more to calculate and display ?

thanks for testing the patch Vichug... you are in MacbookPro 15" Retina too?

i test the patch in a Windows machine with a ATI Mobility Radeon 5700 1gb and it runs smooth at 60fps with poly_mode 1 1

15" Retina have a NVIDIA GeForce GT 650M 1024 MB that i think is similar than the ATI.

i dont know... its a pitty that Apple dont give the chance to have a GPU control panel because i think this is something related to gpu conf

perhaps somebody can illuminate the path?

hah. My macbook is no retina. But on my Windows boot, i might have observed a slightly better performance with a patch using opengl...

aha... the difference to me is from 12fps to 60fps but with diferent machines..

but at the end, i guess that poly_mode 1 1 is less gpu expensive so don't understand such a difference...

perhaps somebody from C74 know something about?

thanks!

"poly_mode 1 1 is less gpu expensive"
i doubt that, since you're drawing more shapes... each line is a shape, as compared to poly_mode 0 0 where you have only surfaces. No ?

I configured jit.window to @sync 0 (in order to be able to see framerates above 60 Hz) and qmetro to 2 ms, didn't move the ititial position and the results were:

windowed (320 240)
poly 0 0: 500 fps
poly 1 1: 500 fps

fullscreen (1920 1080)
poly 0 0: 330 fps
poly 1 1: 380 fps

Max 6.1, Windows 7 64, AMD Radeon HD 4870 1 GB

Pedro, thanks for testing... seems that ATIs or Windows/ATI combo handles better wireframe modes but its really weird such bad performance in MAC with nVidia gpus having similar characteristics.

or perhaps is something related to Max?

because i dont think theres the same issue with 3D modeling softwares in Mac, no?
