Sorry you misunderstand, the process runs frequently when I need to render, so everytime it runs I have to change the priority manually down to a low priorty.
So i would like to know if I can automatically do this, or if there is a problem with my system thats causing the slowing down of the mouse.
Seems like someone else was having this problem:
Very slow keyboard input when rendering with 3d studio max 2010 - Other-Software - Applications
Not sure if you have a Logitech mouse, but...
You may find your mouse moving slowly in some OpenGL enabled applications (including Revit and Inventor) if you are using the Logitech mouse driver. In the current version of this driver (Control panel > Mouse > Motion tab) you can find the "Disable acceleration in games" option. Uncheck this option.
You can also download and run the "Logitech Advanced Settings Utility" for MouseWare 9.76 and above.
No i use a razer deathadder mouse in the usb.
I do also use Maya and when rendering that does also cause the same slowdowns. But using that Prio I can save the priorty to below normal so each time its runs it never uses high cpu.
But because the renderer I use for development is run by script it doesnt save this priorty setting so each time it runs I have to change the priorty down to prevent my system slowing down.
I`m going to go through the bios and check theres nothing obvious.
Thanks
Checked hyperthreading is on in the bios. I also changed the settings to high performance but still no improvements. I`ve also removed quite a few things from msconfig but still getting stuttering. Once it starts it probably takes me 30secs to get to the task manager and reduce the priority its that sluggish causing the mouse to freeze for maybe 5 secs at a time.
Really annoying.
Seems to be a common issue that alot of people have. Usually solved by reducing the task priority. Whats weird is that I`ve not had this problem on other PC`s, so perhaps its down to CPU type. I do have a program that can save task priorities per software but not in this case as the software is run by a script. Just have to live with it i guess.
Thanks
Just as an update. I downloaded a tool called process lasso. It automatically reduces the priorities of certain tasks as you like. It even allows you to change how many cpu`s a task uses. Downside is you have to pay $18 a year.
Making thing work with this new program has got to be worth $18.00 until you figure another way of doing it.
As an update, I had other issues this weekend with the pc and decided a fresh windows install. Now I dont have any problems at all with slowdown,I didnt even need to install that process lasso. Perhaps some driver conflict somewhere.
Glad you got it fixed. Keep a close eye on msconfig/startup/non Microsoft services. Many programs will activate themselves in there on use or updates.
Old post but for the sake of posterity, I'm surprised no one mentioned bumping up "Windows Explorer" process(es) to High Priority in Task Manager; it definitely has an effect on mouse cursor movement. When I'm running something (or a couple of somethings) that I've assigned High Priority to, I also get the lagging, stuttering mouse cursor effect, as if the batteries in the mouse are low, when I know they're not . . . in those instances boosting Windows Explorer process(es) to High Priority does the trick, without having to lower the priority/priorities of the app(s) running in High Priority.
System in question is an i5-4690 on an H97 board, running Windows 7 Pro 64-bit w/8 GB of memory.
