Revit Performance - or Aaaaaaaagghhhrr!!! ( & Logitech)

[Les Therrien]

What the..

I am not sure if this is a hardware problem or a Revit one.
When I hover my cursor over any walls it's like the walls are magnetic and the cursor is drawn to it! This therefore slows down the cursor until I pass the "magnetic field"?

Yes I did get a new mouse along with many other upgrades. But the mouse/cursor does not do this in an of the 5.1 files.

The mouse works fine elsewhere. It is a Logitech Mx 700 cordless optical.
But i think this is Revit related since the problem does not exist anywhere else.

Any ideas????? :twisted:

Les...I tweaked your subject...to make it easier to find in a search. I've never searched for aaaaargh...before but might now :D

Anyway, your issue is the new to 6.0 performance setting available via Monitor settings, Settings tab Graphics Performance...setting it to NONE instead of FULL.

Different operating systems have different info to follow but you may have received a prompt from Revit to change it by now?

There was some discussion of this on the hardware forum.

Steve,

Do you mean control panel > display settings > Hardware acceleration?

Les

[Les Therrien]

Thanks Steve.

I tried that and it works!

Happy Reviting! 8)

yep, thats the one. turn hardware acceleration off, and the problem will go away.

With the ATI video cards around here, if hardware acceleration is set to either maximum or minimum values this behaviour does go away. (Intermediate values will cause that "magnetic" cursor behaviour you describe.) But having the acceleration off is terrible - it slows down your other programs.

I've asked the Revit team what the deal is with the new video subsystem in Revit and haven't heard back yet. In the meantime get the latest video drivers and try full acceleration again.

here is a link for the logitech advanced settings utility, which will also solve your problem if you tell it to enable game detection (http://www.logitech.com/index.cfm?page=downloads/software&CRID=1792&contentid=6034&OSID=1&softwareid=6819&countryid=2&languageid=1)

There have been a number of posts in different forums about this do we think it is a bug or at least a "feature that needs documenting"?

[Wes Macaulay]

Rhys, did the Logitech utility help you? Because that file is for configuring mouse speed and I would not have thought it related to the video problems people are having with R6.

I used another technique and used the problem as an excuse. - I dumped the old laptop and bought a new one with a bigger graphics card memory.
I havent had a repeat of the problem -but then I've only just switched open GL on and haven't used that in anger. i'll experiment with acceleration levels as well and try the utility, thanks.

The logitech utility handles the problem of the mouse slowing down when in Revit. I don't know if this has anything to do with the hardware acceleration thing, but with the MX700, I have had to use the advanced utility to get the mouse to move at the same speed as in other programs.

[Les Therrien]

Greg, I tried the Advanced Utility, and it only made things worse.
What I had to do was uninstall the Logitech installation and use the Windows system driver on the Logitech Mouse.
I tried using variants of the hardware acceleration with the various mouse drivers only to have to keep the acceleration = none. :roll:
Everything works fine otherwise.

Weird... :shock:
