Display is really jerky and lagged

When i play there is no smooth animation at all, everything looks like it is moving under a strobe, even the chat box, really jerky and stepped movement.

im running a core2 system with 2gb ram so i would guess this should be more than adequate how can i fix it up?

Most likely you have a poor graphics card, or have graphics acceleration turned off.

The simplified view in the beta version (Ctrl+Shift+L) helps immensely. Menu animations or the "Rank up" animation for example appear really smooth. I think I will use this mode in future when I don't have to make precise adjustments to the protein.

Not a poor GFX card.

Running
Core2 E6300 @ 1.86ghz
2gb ddr2 6400 ram
ATI X1900XT graphics
Windows 7

All other games like on steamd (portal, TF2 etc) run fine at the highest resolutions, however this game just seems like it moves at 1 frame every 2 seconds.

works fine on the crappy computers that i have in the office, but not on my half decent one at home!

I have noticed this as well, but only since the update.

I have played with it some, and I believe this is isolated to Windows 7.

I know it's not a hardware deficiency. It also works fine on my non-Win7 machines.
2.66GHz C2Quad
Dual GTX 260 in SLI
8GB RAM

I will troubleshoot this more this weekend and post anything I find.

@ Jetpac, do you know if you are using a WDDM 1.0 or 1.1 driver ?

If not, could you post the driver version you are using ?

Well if it helps any, by default, Win 7 installed the 181.20 driver for my nVidia cards, after going to their site and downloading the 185.85 driver for Win 7 x64, all seems to be fine. There is probably a similar download for ATI cards on their site.

Hi–

I had the laggy/jerky display problem as well when I first installed Foldit. I'm running an average PC box with a fairly low-end Nvidia card, under Ubuntu Linux (32-bit). And I was running the Compiz desktop graphics compositing system. When I turned off all desktop visual effects, Foldit ran beautifully, and even the music/sound effects worked.

Until, though, I downloaded/installed an updated kernel, and now I can't get the music/sound stuff at all. I realise some folks find that stuff annoying, but I liked it, and now I miss it.

Aside from that, I love that there's now a great game for Linux! I don't have to go over to the Windows half of my PC to play games (or at least not this game). Good onya, guys!

(Heard about Foldit through the Wired article.)

can you run:

sudo lshw -C sound

this may give a clue…

is sound not working in general, or just for FoldIt ?

You might try:

sudo apt-get install linux-backports-modules-generic
(or find this in the repository, reboot is required for it to take effect.)
