AAarrrrrgggg!
But the screen saver seems to be quite jumpy. Or are that singular pictures?
But they are very pirate-day-like!!!

The validator seems to be off, in spite of being shown as running.
Still no result validated, might this be connected to the hosts problem (in Help-thread)?

Yes, it can be quite jerky. I'm watching it now on an old Thinkpad. It runs smoother on newer graphics hardware.

The animation seems to behave somewhat different on this hack than for others. For most of the others if the hardware is old and slow then the screensaver runs slower, but you still get all the frames. This one seems to look directly at the clock and compute the frame it should show right now. So on an old machine with little hardware acceleration you get single frames in the animation but they are not close together and don't morph from one to the other well. (I should look more closely at the code to confirm it, but that's my best guess right now.)

On a newer box with hardware graphics acceleration it should be a smooth animation, with some nice effects (the logo/sign fade in and out, moves back, etc).

As with earlier screensavers in the starboard series, I didn't write it, I only made small adjustments to get it to run under BOINC, and on Windows. The hacks that come from XScreenSaver were written by a wide variety of authors, and each has it's own little quirks.

I'll say.

My poor crappy onboard graphics coupled with an aging (probably overheating) P4 makes for a series of disconnected images.

It's a little bit better if it's not full screen.

Other than that, nothing remarkable to report.

I would like to remark that my graphics card indeed is very old (about 8 months!)
(geforce 7600 Gt and in other cases working well)

So can anybody see the screensaver scrolling smoothly, as intended? Or do all pirates have old, crappy graphics cards? :-)

It's a lot smoother on my Linux host. It's more jumpy when the window is maximized.

Yep, only crappy graphic cards here.
But I do notice that even my crappiest laptop (IBM 390e - circa 1999 - that will crash running most BOINC screensavers) will run this screensaver with no problems other than the slideshow effect.

C2D T7200, idle ATI X1600 (i.e. no other changes on screen), plenty of memory, Starboards' graphics thread has higher priority (4-6) than other threads, which consume CPU (means other Boinc apps with prio 1).

Nevertheless the Starboard window is delivering only a (scary ,-) slideshow in approx. 1 second beat, regardless of the window size and the CPU consumption (of the graph. thread alone, the app itself is currently suspended due to the STD) varies between 1%-12%, according to the window size. Nothing smooth compared to the green/red Matrix (character) rainfall.

Graphics are very jumpy on my laptop.. 1.6G Pentium M, 512M ram, Radeon 9600 mobility integrated card... XP SP2.


It usually displays graphics very smoothly.

In fact, right now I have Einstein@Home graphics open, with the E@H app running (taking abot 100% cPU), Pirates suspended but with graphics open. E@H graphics are nice and smooth.. pirates looks like a slideshow!

FWIW, I finally found and installed the package that has this particular xscreensaver in it. It ran a lot smoother than when it was running through BOINC.

So Eric, are you taking requests for 5.16? .-)

Indeed, that's what I did. I looked at the rendering loop at how it determines the time of the next frame. It uses a Unix routine called getttimeofday(,). Since this does not exist on Windows I had already written a replacement, but I'm suspicious that my cobbled together version wasn't doing it quite right. I'll replace it and try another round. That could be the explanation for the slideshow effect, not that we all have crappy graphics cards.

Maybe not 5.16, but I'm open to suggestions.

Hey Capt'n, on Win you can use GetTickCount(), it returns the number of milliseconds that have elapsed since the system was started. I think that for our ten minute pirate equipment the time range and resolution are just fine.

That's good to know, but BOINC has its own dtime() function which does just what we need in Windows.

There was indeed a problem with the "fake" version of getttimeofday() on Windows, and that would explain the jumpy slideshow effect. But since I only have crappy graphics cards I can only say that it looks better than before, but not smooth. I hope it's smoother for those with better hardware. Enjoy.
