Spring RTS Engine

While the padding is easy, I don't think the alignment is. In particular not for (temp) float3's created on stack. Maybe there's some __attribute__ for it tho, in GCC? ... never heard of an possiblilty to force stack memory to be aligned (think would be too complicated) ... but you can always align...

Remarks: on 64bit, gcc uses SSE2 by default and I didn't got any desyncs until now. As long as all build keep the same flag (STREFLOP_X87 or STREFLOP_SSE) it should be fine, even with different compiler optimizations applied (SSE vs. SSE3.whatever). I think you may be disappointed at how (not) much...

It does desync if one client calculates stuff using SSE and the other using X87 math or an integer approximation. (If used in synced context, of course.) SSE has different denormal handling then X87 IIRC, meaning everyone has to run Spring with SSE, or no one has to run it with SSE (applies to the ...

What about sync issues and compatability? Remember rattle being the odd one out in the entire community not being able to run with SSE because of the chipset he used not supporting it? And what about differences in calculations between the SSE approximate answer and the fastmath answer which might ...

What about 64bit? possible...but with 64 bit the calling conventions changed and more evil are now different between linux & windows (http://en.wikipedia.org/wiki/Stdcall)... inlining would solve this problem here an 64bit src&compile for Windows (only), same functionallity like 32bit versi...

Indeed inline assembler could be much faster, but I think there are portability issues with that... hi jonanin, yes you are right its seems to be in every C/c++ compiler different to use inline assembly, also support for SSE1/SSE2/sSSE3 etc. might missing. Another problem might OS portability, and ...

nice discussion! :) want to share my experience because i'm working on low level optimizations on my job too... i tried several approaches but ended with writting the very core in low level assembler SSE code... e.g. on the square root for the vector scalarproduct i was able to get an speedup by ~2 ...

someone tried in the meantime for win9x?

*sigh* ... when even doom3 and quake 4 runs on win98se....

v0.67b1, in singleplayermode no units are created (win98se)

on various windows systems (9x-me) on singleplayer startup no units are created

no one get an idea on this problem?
one of the developers?

win 98 is "problematical" and a stability issue. Not runing in these oses, makes spring more stable per se... trying to make it work fine in win 98 is a risk. staying away from win98 is a stability solution already :D thus win 98 is quite old atm, and unstable.. and insecure.. and... why ...

I've got a 9600PRO, so I know it's my operating system. I've still got 98. And until just recently, I never saw anything that said it needed XP. hello everyone i got the same problem and i also use win98se, fully patched, directx9c, geforce 3, 256mb ram. why should spring only run on xp or 2000? al...
