Graphics card performance issue
show user profile  magarlick
Dear all

Last year I built a new PC, with a hexacore i7 running at 4.5 GHz and a GTX970 graphics card. I originally was hoping to use the CUDA capabilities of the latter to speed up rendering but it's slower than CPU rendering. This surprised me.

I am wondering if thiis card is performing as it should. I just created a simple scene, nothing in it except a plane, set to 1000x1000 segs (2 million polys). I get ales than 10 FPS and Max is very sluggish. In fact the entire PC is sluggish when this scene is open.

Is this normal?

Extra info. It's a Palit card, not overclocked, 4GB RAM. Tried several versions of the graphics driver.

edit: I too have a GTX970, and also wonder if it's performing to it's maximum, re: the FPS, what version of Max are you using?, viewport performance only reached an "acceptable" level in 2017, prior to that it performed like a snail with a hangover. Viewports are (single core) CPU driven btw, If you put a 12gb Titan in there you wouldn't see any viewport improvement.

Have you tried switching graphics modes?
I use Nitrous now but on some projects opengl can be faster. Try switching to dx too.
It depends a bit on what happends in the scene, so, many small objects/polys or rigged meshes also can cause a giant drag.

Thanks for your helpful replies.

Yes, I see a massive difference in speed comparing Max 2017 with 2016. In 2016 I get 8.5FPS. In 2017 I get 260. Thanks for that. (However, on my other older machine, I get the same, about 70FPS in both versions).

Also, changing to Direct3D 9 instead of 11 made a big difference in Max 2016 but not in 2017. So it seems that my card/driver has issues with Max 2016.

Cheers.

I find Legacy D3D much quicker in 2016 and better/cleaner transparency, Nitrous shades invisible objects so if your animating with visibility tracks and have the objects in the same place your staring at a blob of blueish shaded overlaps.
Legacy just gives you that slightly shaded Alt-X look, only lighter and more transparent.

@ magarlick

Don't know if you use it already but PowerPreview gives you much more control over your viewport settings.
