slow framerate on windows 7

[Mystery]

I think it is well established to be a problem with windows 7 x64.

[electronicboy]

It's 1366x768, but as I said, it worked perfectly before changing to Windows 7.

never seen that resolution before. try switching it to 1024x768 and running algodoo.

[Livirus]

It's the optimal resolution for my 13.3" widescreen laptop. If I change the resolution to 1024x768 the laptop must create an illution of having less pixels by merging the colors of nearby pixels. But h*ll, I'm out of options...

[edit]...did not work.

[Ivanlul]

Just installed windows 7 and I am having a similar problem, I'll see what I can do.
Yep, same problem. I have around 2.7-2.8% real time even though I have a high-end computer and updated drivers.

@Ivanlul
Let's see if we got something more in common besides Windows 7. Let me see your systemspec.
Belarc Advisor is a pretty handy tool to see most interseting information about your computer.

Motherboard: Gigabyte GA-EP45-UD3R revision 1.1
CPU: Core 2 Quad Q9400
RAM: 4 GB F2-8500CL5D-4GBPK
Video card: EVGA Nvidia GTS 250
OS: Windows 7 Enterprise (64 bit) 90-day trial, version 6.1.7600

edit: never mind, I updated windows and it now works.

Alright, either I'm just really lucky or I've done something right. I'm running Windows 7 Ultimate 64 bit and I have no issues at all with Algodoo. I haven't done anything special, being a gamer and an all around computer guy I keep my computer somewhat up to date. And I don't have extraordinary hardware. So I dunno what to say about that. I've noticed that a lot though, many people have problems with Windows 7 that I've never experienced.

[Matten]

Now I have the same problem. I have windows 7 starter, and first Algodoo worked well, but just 5 min. ago I started Algodoo and it lagged. I think I have something about 10% realtime.

[Mystery]

Delete you config.

[Matten]

This didn't help. And I have the problem only with the "fake" fullscreen and the normal fullscreen. If I make the window small Algodoo runs 100% realtime (but I use a laptop 10 inch, so a small window is really small for me).

[Mystery]

Delete the config in My documents\Algodoo not the one in Algodoo root folder.
If it worked well, then it stopped working it means something has changed.
Also update your GPU Drivers

[Matten]

Yes I have deleted the my documents config, but it didn't help. And when it started I was trying something with materialVelocity (you can do very cool things with it), and I closed Algodoo and when I opened it again it lagged.
And what do you mean with GPU drivers?

[Mystery]

Your graphics drivers.
Try a uninstall and reinstall. That usual fixes most problems.

[Matten]

Does he save your scenes with re-installing?

[Mystery]

Yeah it leaves My Documents alone.

[Matten]

Alright, I will try.

Edit: It didn't work

[Bronie12345]

I'm experiancing the exact same problem. I ran Phun smoothly on my previous Vista installation. Now that I've upgraded to Windows 7 it's really slow. Even an entirely empty scene has unbarably slow framerate.

As it seem to work fine for Mystery on Windows 7... what about 32/64 bit system?
I upgraded from Vista x32 to Windows 7 Ultimate x64. What about you Mystery and nima2007?

[Edit] Oh, forgot to tell you that I'm running Algodoo 1.7.1 after the Win7 installation, not Phun.
[Edit] Tried with Phun too now, same problem.

1. It's impossible to upgrade from Windows vista x32 (or x86) to x64...
2. I also have the problem (windows 7 x64 Ultimate)
3. waiting for the download of my drivers to finish
4. I had this problem before, and it fixed itself after a while (dunno how or why)

Livirus, here's your answer

I have an other windows installation on this computer, windows server 2008 R2 x64 standard
That windows version has (almost) the same kernel as windows 7, but runs algodoo fine (too bas it's on a slow hdd)
