Slow Execution in 64-bit Vista? [RESOLVED]

by Pat Frank · in Torque X 2D · 07/30/2009 (2:29 pm) · 5 replies

Programs seem to be executing very slowly. Movement and sprite animation drags horribly, at a tiny fraction of their normal speeds.

I'm thinking drivers and there's a couple I still have to check, but I was hoping someone here could at least confirm that everything works normally in 64-bit Vista. I gathered from a couple of posts that this is the case but I thought I'd check to be sure.

Also has anyone seen this specific issue, and if so were you able to track it down?

Thanks!

Have you already looked at this thread Pat? Slow frame rate mystery

Running Vista x64 Business and did the SimulateFences thing and all's well now. Before turning on SimulateFences I'd get some random slow down but I attribute that to running SLI and not x64.

I don't think it's actually Vista 64. I have Vista 64 on my laptop and it works fine on and off. It's usually the video card. According to the SimulateFences post it does the following:

Ok, I spoke a little more with Clark on the subject. Basically, SimulateFences is used to keep your graphics card from getting to far ahead in its rendering.. think of it along the same lines as the force VSNYC option most 3D accelerators give you.

With SimulateFences on, you will often get a faster and smoother experience in the game, due to the video card not being allowed to get too far ahead before finishing rendering earlier frames. (It wrangles the texture memory of the card to achieve this)

With it off, you can experience much different results, depending on the video card you are running.. in some cases a fast card can be rendering so far ahead that the simulation will actually be running slower and/or very jerkily due to missed frames.

SimulateFences is used to keep this in check, and is fine to leave enabled.

Hope this answers your questions!

Yea, SimulateFences will solve this problem for you, Pat.

Be sure to add your graphics card to the list on TDN if it hasn't already been added.
