It's not really a game. It only allows you to compare the power of your computer with best computers of other players. Some computers are good for Foldit, other poor. I noticed that Foldit recipe is very CPU resource consuming. I suppose that when a player buys a new computer, he will succeed gaining more points to this test.

1) Click on this contest: http://fold.it/portal/node/995975
2) Go to "Link to join"
Click on "Click here if you would like to join."
3) Open Foldit
4) In the main menu, click on "Contests" on the right pannel
You should see the Contests you joined, including this one. Select it and click on "play".
You'll get a very big protein.
5) Click here above right in order to load this recipe (or, in the recipe menu, type manually the number 46825 to manually load this recipe).
6) Run the recipe once.
7) Your score will rank your pc relative to my best pc I ever tested there
8) Open the right green button on the recipe in order to see the reciupe log. Here you can see some information, for example the CPU time of the first recipe loop. With a better PC, you'll see a lower CPU time there.
9) Save and share the result with yourself or your group for later archive. Whrite there the characteristics of your computer.
10) You might consider adding it here too. This could help people to select best PC adapted to Foldit ... and show that a powerfull PC is good for using recipes (it's less important for hand folding).

the CPU time first loop and the number of loops is the only pertinent results to be compared. Above, the old Mac took 19 loops. It is approximately 2.5 times less powerful than the (new) pc above.

The points are only good for ranking: more point = more powerful computer, but 200 pts is not 2 times more powerful than 100 pts (the points depend on the zone of the protein used for the test). I used a very big protein in order to allow this test last for several years.

I'll add other test results here. Please feel free to add results of other computers and configurations here.

If you save and share your result, when you run the resipe on another computer, previous results are archived in note 1 (and also displayed in the log).

closest "Link to join" is "join contest with magic key", which begets "wrong magic key".

precision wiggle for test
=========================
2nd run, fast wiggle,
2 other clients running
71 loops, avg 8.6 sec/loop
=========================
It appears the choice of fast/slow wiggle is important

With less precise wiggle enabled, the result is as follows:
CPU time first loop: 10.6 sec against 13.2sec with default Wiggle (see above)
Result report: 15141.234 against 15125.471 pts
Total gain: 31.557 against 15.794 (more loops in same time 10' gains more per unit of time)
68 loops instead of 49 loops

Conclusion:: Less Precise Wiggle is about 30% faster and more rentable per unit of time on big proteins

Could this recipe work with other proteins?

Will run again with just the test client open.

ran "normal for me" condition, as one of two clients. ran auto wiggle power default, minimized the protein display to hydro, line and no stubs or sidechains, reduced size and pushed protein off screen
9626.577 in 101 loops with result 7.31 seconds for first loop. so not as slow as Actiasluna with heavy load of 4 clients. my machine speed varies noticabley with protein size. Other client running the 70 AA monocyte
