Sauer X64 Pointless?

Would the effort to compile/port Sauerbraten to X64 yield no benefits, be it performance or otherwise? Furthermore would it break compatibility with 32bit servers?

Yeah, XP is lame that way.

Started dual-booting into Kubuntu 7.04 AMD64 and discovered a nice jump in FPS.

I'm not sure I under stand you eihrul...

I'm under XP X64 and using cmd I can compile the source in 64bit just that easily?

No, you need either VCPP or MingW (or Codeblocks/DevCPP).

Not sure if you're gonna get the answer you're looking for around here, might be an idea to read some tutorials/google on the subject (TIP: this is generally how you learn stuff on the net).

If anyone around here was that interested in (or able to produce) x64 binaries, there'd probably already be a port.

Good luck.

Your "Tip" is somewhat offensive mate, not everyone on here "just discovered the internet".

I was just hoping to get some insight from Eitrul or Aard on the subject. I know how to compile Sauer under linux, I just wanted a quick windows solution.

There is no "quick solution". Get the source, a compiler, and there you go.

*sigh*

My point is that there are tons of resources out there on the net to teach you this very thing. We've all gone and spent the time to learn the things we do, and seriously learning anything is certainly never "quick".

We're a small community and we don't have the resources to sit down with each individual personally and teach them how to use the engine in the way that they desire, there's just way too many of them kind of people.

You may think of it as offensive, but it was merely a subtle reminder that those resources are there for a reason. I do quite a bit of development under Windows, and I pointed you in the direction of the utilities I have found the most useful in compiling Sauer (and to be more specific, Codeblocks is very easy to use for straight-up compiling because I maintain the project file for it).

Please settle yourself and remember we all have lives too, hey? :)

"Please settle yourself.."

I swear man, it was a simple question and you have go and act all superior.

If I was that concerned about it I would have done more research. My primary concerned was client (64) side incompatibility with server (32) side. Which cannot be answered because it appears no one else has done it.

I've been a part of this community a long time, and even though we have some ignorant people on here from time to time (i.e. people announcing a new game or mod) we shouldn't react as if everyone doesn't know what's going on around them or how to find things out.

Quin, maybe you are trying to help and for that I commend you.. but don't be so cocky man. It only rubs people the wrong way.

Further more I'm going to give Codeblocks a try, thanks for the tip.

Sauerbraten compiles fine on a 64-bit computer and the binaries can connect to 32-bit servers. What else do you need to do to "compile/port Sauerbraten to X64"? :-S

Yes, it does compile and run ok, but I have seen some posts on this forum about having trouble with 64bit bins. Bottom line is, if you're running a system that has a hard time running sauer, more than likely, having a 64bit bin is NOT the thing you need for better performance.

My vote goes to the name of this thread..."pointless".

it's indeed pointless. Use of actual 64bit mode will SLOW THINGS DOWN rather than speed them up, because the only thing that does on a program like sauer is double the memory usage for pointers.

64bit is cool because it allows access to more than 4gigs of address space at once, but if your app doesn't need that, it is of no benefit whatsoever.

The only reason 64bit compiles can potentially give a speedup is because the x64 architecture actually also adds more registers, but this feature has nothing to do with 64bit-ness. If amd/intel had added extra registers to the x32 at some stage that would have been even faster.

Oh, and like eihrul said, your 2% speedup will sit idle waiting for the gpu anyway.

I kinda figured it wouldn't be of much benifit, but I'm always curious about these things.

Many thanks, and as an upside to all of this I've started to compile Sauer on my own now. *puts on big boy pants* ;)

Running the 64-bit binary on Ubuntu averages 120 fps or so.

Running the 32-bit version averages avout 112.

So my guess is yes, the 64-bit binary is somewhat faster.

It "feels" faster.

i always missed a benchmark mode in sauer when playing with compiler options or features like multithreaded opengl.

Not that great an improvement over x86 sauer on the same processor.

I compiled sauer on x86_64. I recently built a pure 64 bit Linux from Scratch system, with no 32 bit libraries.

I would say no, there's no benefit to running it in 64 bit mode, and if anything, some maps seems to be a little slower. I don't quite get the full 200 fps in maps with heavy shader/bumpmapping use. Close to the same performance, but not quite.

That may just be a kludgier Nvidia driver for x86_64 though.
