I noticed something strange: There's a lag in windows when I hold and drag the mouse for selection rectangle, but only when I keep CTRL or ALT or SHIFT pressed along with the mouse button, there's a lag even with this simple rectangular marquee in windows, the movement gets frozen every 2-3 seconds.
And when I hold and drag for rectangular marquee with mouse button only, there's no lag and it's smooth as it should be.
Same behavior in 3D softwares: lag when using mouse button + ctrl or alt or shift, and NO LAG when using mouse button only
CTRL, SHIFT and ALT are the cause!
But the problem now is how to fix that? I want to use the alt or shift or ctrl key along with the mouse in my 3D apps, it's so convenient and useful.
I disabled tablet input service and it doesn't help
well combat wombat, I want to thank you for your help, you've been patient, and it's certainly a good quality of behavior, may God keep this with you all the time.
Don't bother anymore about this, I'll be fine (lol)
"I think I found the cause of the lag effect in 3D viewports.
Since I saw that it was not 3dsmax related only, but also in vue app., I began to think that something was wrong with windows and the mouse.
And I really think now that it is the cause."
lol, this my post on evga forum
Finally, my problem was fixed. A evga sr-2 user gave me a tip that it was the eleet monitoring software that was causing this lag. And it worked, I just avoid running it when using my pc.
My pc is working well now.
Thank you combat wombat, I hope I could help you in the future
