Bri (Buddha) has noticed that VP3 runs as a low priority process under Windows. Even if you changed the priority to Normal, then VP3 changes the priority back to Low every 3 seconds or so. Is this something that is coded into VP3, or is it something in Windows that is altering the process priority?

For those who wish to keep VP3 running in Normal priority mode (or any other mode for that matter), then see http://www.polomint77.co.uk/vp3priority.html

Thanks.

There was an issue with VP3 not responding well online when throttled. I think the lower priority is only in windowed mode but maybe you could confirm.

I have checked VP3 using windowed and full-screen modes.. The same applies. VP3 throttles the priority back to Low whenever it is changed. It doesn't really make much difference, but someone mentioned it to me, :) (can't remember who though...)

I looked at the code, VP3 does change priority to IDLE_PRIORITY_CLASS which is much lower but only when it is not the active application. If your using another windows tool to look at priority then VP3 does is not the active application and will be at IDLE. When VP3 is the active application it has NORMAL priority.

Is Idle? the same as Low? Thanks for replying, we just wondered about the priority. Any chance you could release some of the code, :D hehe hmmmm, maybe a community edition where we can mess with a certain version code? 3214 anyone,,, heh

I can confirm with 100% certainty that vp3 does switch process priority to low at all times, regardless if it runs as desktop window or full screen. That problem has been annoying me for many years, the issue is noticeably affecting VP3 performance on older, slower computers. It stopped affecting me so much when i got new and very powerful notebook, where even at low priority the game runs smoothly.
@ vpeer: the easiest way to check the process priority in full screen is to run the game on a system with multiple displays - that way, even when the game is in full screen it will still occupy only your primary display and you'll be able to see process priority on the other displays, without exiting full screen mode or switching the focus away from the game (it'll still be the active window). I use Sysinternal's Process Explorer and Process Monitor for such purposes. Sysinternals recently became a part of Microsoft's Technet and the program author Mark Russinovich is a former Microsoft employee, familiar in depth with the very core of Windows OS. The reason I'm saying this is to make a point that these tools don't lie - if Process Explorer says vp3 priority is low - that's what it really is, no matter what you find in VP3 code itself.
