waynes ground up

#1

Wayne,in the ground up series you mention the gpu indicator and the fact that mud will suffer if this exceeds your onboard gpu ram.

this makes perfect sense.However,I’m running mud 09 with an 8800gt with 1gig gpu ram and my indicator never goes higher than 31.

i’m purposely pushing mud but at 8 mill faces it’s eating up my virtual ram and bringing the app to a halt.(and preprocession on load is set to 1 also)

i wonder have you any idea why the gpu maxs out at 31 and bypasses to my machine ram physical and virtual?

i’m using mb 64 with xp 64 sp2 and 2gigs of ram with dual core 3ghz intels.

Cheers for any advice mate.

What size is your page file in Xp? Its not a big / error I’ve came accorss so far, so its not something that’s common. I take it this is happening with every model including the ones that ship with mudbox in the create panel?

wayne,my page file size is 2500 and yes,i’ve tried it on everything from the tree stump to the reptile:scream: aswell as some imported meshes.

It seems odd that mud would ignore the large gpu memory and eat into the virtual considering it’s a viewport issue.

I also soft-modded my card to a quadro and this still had no effect.(unfortunately i had the bad luck of my card twinning with a feckin quadro nvs 290!!!.although i have to say max 2008 64 is throwing 3.5 mill faces around without dropping many frames.:slight_smile:

cheers for the advice mate.

just tested it there with task manager running.keeping an eye on it whilst sud-ding the mesh. Pushed it to 34 mill.Now it took about 10 min to jump to that level and 3/4 way through windows requested additional vir mem.i was able to navigate and sculpt with a 1-10 sec delays depending.but, no matter what, the gpu memory didn’t budge??

autodesk clearly state that at least 512meg gpu is required.Why is this,if mud isn’t even going to use it?:curious:

the gpu ram is used for texture painting… all texture stuff is gpu related in mud…
try to paint 5 tiled 4k textures and you will see…

#5

Thanks for that oglu but i’m not entirely convinced.Surely it would make absolutely no sense whatsoever to have 1 gig of gpu ram sitting idle whilst sculpting.:curious:

#6

Also,just added an extra 2 gig of ram to my setup today.Mudbox is completely unaffected whilst Zbrush is noticeably faster.:blush:

I understand that mud is aimed at professionals but this is ridiculous!! It dosn’t make any sense to me at all.(see my post above)

Mudboxes ease of use coupled with the exciting Wayne Robson series that we’re all looking forward to(hint,hint:pgive us more wayne.:slight_smile: has got me so hyped up that i’ve held back on the bills this month and upgraded ram and gpu.At this rate i’ll have to sell a kidney to run Mudbox smoothly…

4 gig ram DDR3, 9800 GTS 512mb, intel duo 2.26GHz. runs like a charm up until about 22 mil polys. on a laptop. texturing can get somewhat sluggish now and then, but I am super-duper impressed by Mudbox’s performance tweaks.

I don’t see the problem with running Mudbox on a normal set-up?

#8

well,that’s almost identical to my setup.this i find very relieving.have you been keeping count of your gpu usage in mud or your page file limits in task manager whilst using mud?
I’d be very interested to know your maximum usage of both.
And you feel that at 8 mill polys,for instance,mud still runs at 70-100 FPS? with no lagging or skipsteps?

#9

I haven’t taken any particular notice, but I’ll keep this in mind for the future and get back to this thread when I’ve found out more. :slight_smile:
