vrayproxy viewport slowdown

[zeronove]

anyone experiencing tremendous viewports slowdown using vrayproxy?
I'm trying with a gtx570 and they are almost unusable if not in box display

[vlado]

Which 3ds Max and V-Ray version is this?

Best regards,

sorry I forgot to mention
3ds max design 2011 x64
windows 7 x64 pro
VRay 2.20.03
geforce gtx570 latest beta driver

Hm, ok. It would be useful if you can get us a way to reproduce this - from my tests here it doesn't seem too slow, but maybe my scene is too simple.

here it seems to happen with simple scenes as well

http://www.mediafire.com/?mz8kycj16u34k9m

without proxy (1024 poly) I have 350 fps
with proxy (160000 poly) I have 3.5 fps

orbit in full viewport and smooth+highlights without any degradation

I can add that the proxy was made time ago with a previous vray release

any idea?

[vlado]

any idea?

Not right away, will have to debug it to see what's wrong.

does it mean that you can reproduce it there?

[zeronove]

vlado can you please confirm that it's a vrayproxy problem? ...it's just to narrow a bit what's wrong with this new gtx 570

[vlado]

With GeForce 580 and the latest drivers on 3ds Max 2012, I get between 150-200 fps in the Nitrous viewport, about 3 fps in DirectX mode and about 19-25 fps in OpenGL mode. So it does look that proxies draw slowly in the DirectX mode. I don't know the reason for the slowdown yet.

ok, thanks for the infos ...let us know if you find a solution, for the moment I can switch to box mode

[zeronove]

Vlado, I've just found something that could be useful:
importing as mesh one of the old proxies and redoing the entire proxy creation process leads to a scene where the preview from file (edges) option is extremely slow as previous but the the proview from file (faces) is a lot faster, I'll dare to say tedious but almost usable.

[zeronove]

any news about this?
if yes does the fix will come with a future sp or sooner?
managing older scenes with this new gtx its a pain (backface culling and vrproxy slowdown together are an overkill)

[vlado]

We will try to improve this, but it's a lot of trial and error...

gasp! so, no hope?
suggested alternatives?
do you know if does it happen using a quadro 600 or 2000 as well?

I didn't say that I just said it's trial and error, so I can't get you a quick solution unfortunately.

I don't know yet; we have to try it out on a Quadro card.
