Development

Think performance on the CPU should be worked on first, cuda and opencl dont work on all gpus.

For example 3DCoat including a few .exe - CPU and GPU. Also it's will can to do for NVil.

It is a combination of not being as optomized and that c# isn't as fast as c++ performance wise.

C# is not best choice for a heavy software. I hate this technology =).  But - no c# -> no NVil

Can you be more specific as to what viewport performance issues you are having?

rubberDuck above wrote about it. I'm don't played with a big number of polygons. Now i'm subdivided my ex-ussr(not finished) car under 11000 poly and when i zooming -> a lags.

For me another is important: 100% cpu even if i just clicking on the viewport.
there are 3 of variants:
1. My PC is very very old - Athlon64 3000, 2.5 gb, 8600gt
2. A bug in NVil
3. the .NET technology.

OR 1+2+3 =)

11000 polygons is not really a lot of polygons for a sub-d modeler.

Unfortunately, we still do not know the minimal or recommended hardware for Nvil.


I do have a single core Athlon64 system boxed away. I will get it out at weekend and have look to see what Nvil is doing on that hardware.

What windows OS are you using?

What windows OS are you using?

WinXP SP3

Now i'm subdivided my ex-ussr(not finished) car under 11000 poly and when i zooming -> a lags.

more precise:
a little lags when i zooming. When i rotating all OK.
I have a realy weak PC and I have no complaints I wrote it only for:

For me another is important: 100% cpu even if i just clicking on the viewport.

If there is a bug, fixing it can affect performance of NVil and on(to?) other PC.

a little lags when i zooming. When i rotating all OK.

Which zoom function do you use?

Alt + RMB
MMW (wheel on mouse)
view window corner navigation option with RMB

or is it the same problem which ever zoom you use?

Unfortunately, we still do not know the minimal or recommended hardware for Nvil.

I think that my PC / any Celeron -> minimal hardware =)

Which zoom function do you use?

I tested again (all the 3 of variants).

A little lags(when rotating also, but rarely/) happening when using CPU amount to 90-100%

Hm..Interesting that peak of CPU happening when i just moving a mouse under clear(empty) viewport (i created a new scene).

summary: The weak PC or bug in NVil.

---update---
1. Increased subdivide under 23500 poly
2. Maximized a "perspective viewport" - ok
3. Enabled a four viewport -> zooming in-> zooming out -> quick rotating (alt+LMB) ->a little lag

It may be your GPU(Graphics card).

What % of your GPU is being used while rotating/zooming view?
(you can use MSI afterburner http://event.msi.com/vga/afterburner/download.htm to check).

Thanks steve for idea. Recently i have a strange problems with video (using GPU for acceleration). I checked the videocard some a program. Tomorrow I will try the afterburner and will install a other drivers.

I tested the my 8600GT in MSI Afterburner(Kombastor).
Results:
Max temp in Kombastor - 65C . Time of test - 45min.


Temp in NVIL - ~45C .
Max GPU load - 40% when rotate/zoom 93500 poly

-------------
A new test -> new information:



* Selected = my object is selected
  No Selected  = not selected

--------------------------
The selected object or no, but a CPU always 95-98%

Maybe bug/no optimization in NVil when select a object?

Hi molebox,

What .net framework do you have installed?

Hi steve.

I have a .NET 1.1  , 3.5 SP1 , 4

Do you have such problem?

Do you have just 1 object in the scene? If you have more than one, have you tried turning off "View > Object Shading > Show Edge On Unselected"?

Hi Vaquero.
I have one object in the scene - body of car (366 poly) which i subdivided as wrote above.

May be IStonia will read the thread.

Vaquero, I am satisfied with the performance of NVil. Just may be I help it to increase =)

Hi molebox,

I have not seen that. I clear my browser cache each time I close it.

Which browser are you using, and do you clear your cache?


.

I have a .NET 1.1  , 3.5 SP1 , 4

Thanks for all the info.

I set up on a:-
AMD64 3800+ (2.39)
2GB ram
(onboard) Radeon HD 4200

When switching between view rotate(alt+LMB) and Zoom(alt+RMB) I was seeing a delay of about 0.5 to 1 second before view would rotate or zoom. But once view was rotating or zooming there was no lag. Are you seeing similar?

I use chrome. I was cleared the cookies, cache.

Where did you get such a rarity?

exactly! =)
