XSI Lag ? Any solutions ?

[bsm3d]

Hi,

After playing with XSI on a basic model (ground, chairs, desktop,...) a small office room, XSI coming slow to refresh viewport until it's impossible to continue modeling in right conditions...the only way I found is save my project, quit xsi and restart it.

After a restart and loading my saved projet xsi look like better perfs on viewport refresh, modeling, manipulators,...

This lag coming often when switch from wireframe or shaded to texture / texture decal.

If I add multiples UV and image maps, xsi again goes slow refreshing interface...

I found this also coming when add many modifications to geometries like bend, merge, poly extrude,etc...

Have you some tips or tricks for me ? I'm working with foundations release.

The point where i'm in doubt is the Gigapolygons, when loading 3.6 millions polygons model into xsi all goes very fast and fine but when try to modify my model perfs fall down :(

Thanks for you help.

Note : My computer is fast one with dual core 3ghz, 4 GB, 64 bits system and latest video card driver for Geforce 7950 GT.

which drivers?

and remember you are running an uncertified card.

Hi,

Thanks for you reply, my drivers is the latest Nvidia official drivers for Geforce 7950 GT : 169.21 - 512 Mo - PCIe.

About certified graphic cards I don't agree with this business of certified gfx cards, but it's my own point of view and past experience with certified quadro FX 700 who don't do really more for the price difference and burned after 2 months...sorry...

So on my others computer with an ATI FireGL V7000, I also have this lag...

ok...

latest isn't always the greatest. nvidia can introduce a bug that affects xsi. so you need to try other drivers.

the best bet is to get the certified drivers which are currently 91.36 (old i know) but since you dont have a certified card there is no guarantee you can get proper support from softimage. i didn't say non certified cards wouldn't work, my personal machine has a consumer card but my work machine has a quadro fx and it runs way better :)

Hi,

Thanks I will try to downgrade my drivers to check out if I get better results ;)

What's you conssumer graphic card ? and how many polygons you can handle in xsi with a good feedback on modeling ?

I don't say certified card is bad but my own experience is bad ! I spend a lots of pounds in and don't get really better results...may be the prices difference was in drivers quality ?

my desktop has a 6800GT (cant be sure which drivers i have at this moment) anything below a million is fast. i also dont try to go out of my way to work on a model that is 2 million+ polys. there is no need to do that, that is what mudbox and zbrush is for. i also know that many polygons on a single character/object is rarely necessary for production.

dont look at what you dont need to look at, this simple concept can be aided by a naming convention and layers.
