Test Programs

NightWare · June 08, 2007, 08:31:33 PM

hi all,

here, noting to see with speed test programs (in fact, not directly), it's just programs to test some of my algos, i post them because it could be interesting for someone who whant to understand mmx stuff... i hope...

1) Demo_Starfield :
it's a draw line/point test (i've already posted it, but this one is, for several reasons, a bit better)

2) Demo_Sprites :
it's a draw sprite/gfx string test (i know, there is a lot of "asm code" for sprites, but those codes are NOT asm code !, it's just poor win api calls by asm, you must admit it's completly different...)

ho... and, as always... it's in french... apologies... :red

Thanks for the demos.
On my AMD 2500 Sempron, with 1.5 GB ram and ATI 9550 video card, I am getting 144 FPS for the starfield demo,
and 154 FPS for the sprite demo. Are these good results for your demos?

:dazzled: no idea... i've just 40 fps on my celeron 700, or 130 fps on my P4... both are obsolet machine, but it's better to produce really optimized code...

the purpose of those programs is to quicly draw stuff on screen without using gdi/direct draw/etc... and without the need of an expensive gfx board. so if you consider the fps result is acceptable then it's acceptable... :wink

I'm getting ~147 for starfield and 255 for sprites on an Athlon 2600, 1 gig RAM and ATI 9600 Pro on XPHSP2 - the sprite demo sticks at 255 - could it go higher?

askm · June 10, 2007, 03:37:48 PM

The Starfield works with no error message.

The Sprites does not.
Windows 2000, Service Pack 4, Pentium 4 CPU 1.6GHz.
Message:
Program Error
Sprites.exe has generated errors...

to sinsi,

255 ? in that case i suppose you speak about the sprite alpha (you can increase/decrease it with pageup/pagedown keys with a step of 8), so it can't exceed 255. otherwise there is no fps limit (in fact there is one, but it's 7FFFFFFFh)

but in that case, it seems you can't see the moving "fps" gfx string... and i don't known how it's possible...

to askm,

i haven't win2000 OS, can you give me more informations (for example with ollydbg... where the problem happen...)

to all,

wow, it's seems there is problems with sprtite demo... anyone else has a problem with this code ?

Oops, excuse my French - it was late, I was drunk, etc.
Yes, ~153 fps for sprites.

it clearly appear the problem doesn't happen inside my code, so it's win2000 (coz i'm pretty sure of my code... and it work on another OS...), so there is a prob with a win 2000 api... i'm going to suppose all the api do their job (yeah... i known i souldn't...), so it's possibly the interaction... humm... register preservation ? (in theory no !, coz the rules are clear since win nt... but laws and microsoft...), so i quickly made a macro and replace all invoke by Invoke2000 (with theorical unnecessary pushs pops)... askm, can you test it ?
i hope it will solve the problem, otherwise it will become difficult without win2000...
there is no slowdown coz none api are used intensively in this code, and this one should work even on win9x...

Just tried sprites on win2k/sp4 and crash! here's what the event log said

i've updated the version for win2K

i haven't win2k, but i have an old version of win98se, so i spent some time to install it... i've fixed the code for win9x... and i hope it's also the case for win2k... as expected it was a register preservation problem... but it could'nt been fixed by the macro i've previously made... coz it was situated inside the windproc...

i hope it work for win2K now... please test it :'(
