I'm brand new to the game, but the install went well and I'm already impressed.

Until I hit the first mission with a jump node.  When the node is onscreen or even targeted my FPS drops dramatically.  In missions without the jump node, things go great.  (I am NOT using the hi-res VPs).

I suspect it's not the rendering issue talked about in the FAQ, since the same behavior occurs if I simply target the jump node when it's offscreen.

Any advice would be greatly appreciated!

Ah.  Thanks for the pointer there. 

Specs:
CPU:   2 x Intel(R) Core(TM)2 Duo CPU T5800 @ 2.00GHz (1600 MHz) Cache size: 2048 KB
RAM:   2.91 GB
Ubuntu 10.04.2 LTS

Intel integrated graphics chip (gak)

If the targeting thing didn't cause the same slowdown (the second set of framerate drops is me facing the wrong way and targeting the jump node), I'd simply chalk it up to the graphics card.  Buuuuut...

I can't recall exactly what the FSPort hi-res .vp contained but perchance try running without it.

Set the game and your desktop to 32-bit colors. I wouldn't name that as the cause of the issue, but generally 16-bit colors are more prone to cause errors.
Edit: and your resolution to at least 1024x768. If you haven't experienced performance issues aside from this jump node issue, you should be able to handle 1024x768 and it would make playing some mods easier.

Other than that, this does sound weird. Jump nodes are supposed to be (relatively) very simple models without textures. There shouldn't be any reason for them to cause slowdowns.

Something about this issue rings a bell, but I can't for the life of me remember what it was or how to solve it.

This came up after some googling. Among other things mentioned there was a suggestion to use the -no_vsync command-line flag.

No change.

Oh, yeah.  I'd dropped both in an attempt to see if it was the graphics rendering.  Decreasing to 800x600 gives a slightly higher FPS during the effect, but we're talking 10FPS instead of 7FPS.

So it should look like a big outline in space, yes?

And no dice with -no_vsync either.

It should look like this (actually the shape is slightly different in FS1/FSPort than in this image but you get the idea). According to the FS universe, jump nodes are invisible and are merely locations where a ship can enter the subspace corridor between two nodes, or two solar systems. The green grid thing is just a HUD representation so that you know where it is.

Try the -novbo flag. Might help a bit.

[uriel1998]

No luck with -nobovo.  What did it (finally) was using the software mode.  Still had a FPS drop, but it was only to 25-29FPS instead of 2-10 FPS.  Still quite playable.

Again, seems ONLY to be the jump node.  Next mission (so far) going just fine.

[uriel1998]

And it was only that first two missions with a jump node.  The later mission (Hammer &... crap, I was too into it to remember the name! The first one where Hammer of Light appears) ran without a hitch despite the jump node.

[Mongoose]

Man, that's really weird.  It's good to hear that software mode worked, but it won't be the best long-term solution; you've basically reverted the game to pre-HTL rendering, so you'll probably experience poor performance in any mission with a decent number of ships.  Hopefully the support gurus can come up with something more permanent.
