Hi.
I can't get a decent performance out of TS 7.5.
I don't have the greatest graphic card, only a 7300GS.
However, not only the graphic showing seams sluggish - the interface also seams sluggish.
Yet, the dual core CPU that I have isn't directly working its ass off. One core seam to more or less idle - is dual core of as a default and how can I turn that on in such case?
Best regards

Sounds like there is more than meets the eye here - that card should give good enough performance I believe as it should be DirectX9.0c compatible and PixelShader2.0 compliant.
Dual core shouldn't pose a problem either, Windows should decide how and when to allocate work to the cores to keep things moving along nicely. I havent had to do anything to my dual core to keep things running well on tS.
So the next questions are - how much memory do you have, what Windows are you using?
It does sound like a graphics card issue. I guess that question arises too, have you got DirectX9.0c installed? Even though your card supports it, doesnt mean it is always installed :)
With some more info, we might be able to find out what is going wrong! Oh, and is this the demo, or the full version too btw?
HTH!

Hi.
I have 2 gig of ram installed in the system.
My Directx version is 9.0c (4.09.0000.0904) according to dxdiag.
CPU is a Core Duo on 2.13 GHz.
The GPU is a Geforce 7300 GS with 512 mb ram onboard.
Of some reason, TS is slow.
Rendering is quite fast, but the interface is slow in its response. Do I need to update my GPU? Is the interface dependent on the GPU? I get that the 3D view is dependent but also the interface? |

Not sure what you mean by interface is slow. If you mean switching modes, it can take a few seconds with an empty scene on a 7900GT. If you are working in model on a busy scene, turn the bridge off and watch it improve dramatically.
In workspace, fur can bring my PC to it's knees...:o
other than those...I have no idea...:confused: |

Are your graphic card drivers up to date? I just installed 93.71 and noticed a performance boost and smoother shadows it seems.

The interface is most definitely driven by the GPU, but the 7300 should be fine. I was running on a 7600 for a while with no problems.
A description of what is slow would be useful though - screengrabs too, if you are in a complex scene. At the moment, I am not sure if you are finding it slow moving around in the 3D scene, or slow when you click on a button, or if you are seeing buttons redraw one by one rather than refresh instantly, etc.
Sorry to keep asking for more details, but it's the best way we can try to help, if we understand fully what it is that is happening :)
Thanks!

the interface also seams sluggish.
the same thing I feel too.
Mostly the stack panel switching but also working with tools (activate/deactivate) is slow from a sensitive manner.
The best difference you see if you do a test with Blender :D
the gui speed difference is noticeable. |

I am running a nVidia 6800gt on a Windows XP Pro system with a hyperthreaded CPU and 1gig of RAM but don't have any speed problems. Maybe Windows itself is slowing down? |

I think Parva makes a good explanation of it.
I am not sure how I could make a screenshot of it.
For instance, switching between library and settings tab feels slow.
It is hard to explain exactly how but if I compare it to TS 6.6, it feels less instant.
The strange thing is that I feel this with only a simple sphere in the player window. It also feels about the same with a complex scene loaded from the library - so it don't really feels like the scene matters as much as that the interface simply feels a bit sluggish by nature.
I am not sure how to explain it better.
My hope was that there was some kind of setting that I had missed to trigger, since my cpu don't seam to work itself to death (mostly idling). |

When I first got TS 7.5 I found that things were very slow. I had to go to older gfx card drivers to sort that out. Today (I have an Nvidia card) I have updated to 94.24 and this driver seems just as good. These are dated 31st May.
Hope this helps you.
Cheers

There are two types of process to getting stuff on screen, 3D draw processes and 2D draw processes.
They are handled separately in hardware, so it is entirely possible to have fast 3D draw processes and slow 2D processes - the result there would be a slow 2D interface for icons and panels and windows, but a fast display of a 3D scene.
We are continuing to look at optimising the speed of the 2D aspects of tS, it makes sense now that you say that is what you are describing. I would say that upgrading your graphics card is not necessary in that case - as far as I am aware, there are no cards that perform better on the 2D side of tS than others. If you were seeing sluggish 3D performance, that would be a different issue.
2D stuff all comes down to windows management and the like, and we are continually working on that for both speed and functionality - you'll note that what you can do with windows and layouts and toolbars is MUCH improved over earlier versions of tS, we have a much more flexible system in place for the UI - of course that means more complex, which means an ongoing need for us to keep optimising and improving, so more work for us, but bigger benefits for the users ;)
HTH!

I dont find TS very demanding on the CPU, but I do find it very GPU demanding. I work at home on a x2 3800+ with a older x1900xt with 2gb ram and it responds very nimbly. Nothing feels unresponsive and it's a pretty old system.
However at work I have a x2 4600+, 2gb ram and an older x800GT. This system, having significantly less GPU but more CPU (not much but hey, more), feels very sluggish. The workspace display is clearly bogged down.
Both systems are XP Pro, both systems run a 24" dell widescreen. The x800GT just can't keep up at 1920x1200 and it makes the whole interface feel very boggy. |
