I have an older machine that we are trying to run Inventor 2013 on. It gets really sluggish after using it for a while. . With the Windows Task Manager running, when I open an empty idw sheet, Inventor uses 100% CPU just by moving the mouse around on the screen. Of course, when I stop moving it goes back down to like 2%.
This machine is running XP (4GB ram). I am running with the \3GB switch active. Processor is a Pentium4 (3Ghz). Under Control panel, System Settings>Advanced tab, I have disabled all the Windows Visual effects. Also set the virtual memory to 4Gb.
I have tried it changing the Inventor "Software Graphics" in Tools >App options checked and unchecked and it does the same thing.
The video card is a ATI Radeon X300 (128MB) with the latest driver. The card is not the greatest (by a long shot).... I know, but we are only trying to do really simple stuff on this.
Any ideas on why Inventor takes so much processor just with the mouse movement?
Did it run OK with older versions of Inventor?
Does it do this with any other software?
Is windows fully updated?
Is the mouse driver up to date? (might as well check all drivers)
What shape is the hard disk in? I had a colleague who was having terrible performance on his older machine. I took a look and noticed he had <1MB (yes, MB) of free space. Cleaning up his HD helped considerably.
You could also try setting free space allocation to be managed by Windows instead of a fixed size. I generally recommend people do so, anyways. I think AutoDesk recommends it somewhere, too.
It ran "OK with inv 2010 on it. But this is worse. Sometimes I have to stop what I am doing and let it "catch up". Really annoying.
Doesnt do it with any other software. With Autocad, the usage goes up to around 15% when moving the mouse around.
Plenty of HD space.. over 100GB free.
I will check the mouse driver and let windows manage the memory.
It's been so long since I've had to do anything with XP. Next you'll be trying NT4.0
and paste it right below the line.
Edit the pasted line to add /3GB before /fastdetect to read like multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Micro
Probably the biggest problem with XP, will be that it doesn't take advantage of DX11. If I remember correctly it only runs DX9
IV is a real graphics hog.
My boot.ini looks like this.
Systems runs good for about 10-20 minutes while working in Inventor. Making small (really Simple) idws. Then it begins to slow to a crawl and is unusable. Reboot and repeat. Don't think its a heat issue, since rebooting fixes it temporarily.
The 100% CPU usage might not be related to Inventor slowing down, that might be "normal" for 2013 running on a XP 32 bit system.
I might try setting the user variable down to 2200.
I might even try downloading the latest mouse drivers and do a complete un-install of the mouse drivers, reboot and install of the latest version drivers.
