Good work!

I like the "A few other optimizations" part.

This could be very interesting!

I remember back when 4.1 fared slightly worse than 4.0 setup with 3D performance (YMMV), but already with updated 4.1 and MiniGL (2.3) this was no longer the case. Nice to be done with these loose ends.

Pretty cool ! Will do today some actual benchmarks , just for see if there any visual difference or not.

But in any case, optimisation work in 3d area its very welcome

Good to see more updates to MiniGL

lots of stuff to do for me, I still have to upgrade my Sam with the last Acube patches, then this, he he (finally I'll have some time for Christmas)

@All

Btw, its those optimisation was done by Hans or not ?

Anyway, sorry to disappoint , but i tryed LodePaint with new minigl.library : FPS 100% the same (not any differences), but it start to be even worse : while you operate with lodepaint windowses , everything freezes on milliseconds. I.e. you move cursor, its ok for 1-2 seconds, then freeze on 0.5 seconds, then continue moves. And all the time like this.

Will try Cube for now.

With cube no differences in terms of FPS. Well, maybe if only a bit. With 2.3 at some map was 39-41 fps, with 2.4, stable 41 and sometime 42 fps. I.e. 1 fps of difference. But problems with lodepaint now pretty heavy (unusable when you try to work with menu windwoses).

And the last benchmark, just to summarize:

minigl 2.3

9/0.Work:a/CubeBM> Cube
6656 frames drawn in 8.0 seconds
1316 fps (0.760 milliseconds per frame)
841 fps (1.188 milliseconds per frame with swap)


minigl 2.4

8/0.Work:a/CubeBM> Cube
7621 frames drawn in 9.2 seconds
1342 fps (0.745 milliseconds per frame)
841 fps (1.188 milliseconds per frame with swap)

A little faster (the same as cube-game), but difference are pretty small. Imho for the moment not worth of updating for those ones who use lodepaint. Imho that "little freeze" can happens as well in other opengl apps.

@ kas1e

thanks for the updates! sound like it's not worth upgrading at this point

From m3x

And yes it is only a minor update but better than nothing

Yep, if only there not freezes when you leave mouse cursor from and to lodepaint window. I will write mail to Hanz for now, hope he can fix it.

Just to make thinks clear, that how bug is happens now (will be cool if someone else can try that as well, just to see on which HW it happens, on which not happens and so on):

When you run LodePaint with new minigl/mglut library, and trying to open any window in programm itself (for example image/rescale), and then, trying to move mouse cursor away from the working opengl window , the whole system "freezes" at 0.5 seconds and after that little freeze, continue to work. The same happens if you will try to move cursor from desktop to working opengl window back : the same little freeze (like fighting for the resources are happens) and then all works nextly.

Can anyone check it ?

thanks for xmas present :)

I wouldn't call anything running >1000 fps (especially on "lower end amiga-compatible" gfx cards) a "benchmark"

Usually these are really far from any actual usecases. As I don't know this particular program, I'll explain why using glxgear as a benchmark is a really bad idea, I am pretty sure some points apply for this case aswell:

1)What it does is really far from most usecases (non-textured non-animated low resolution models, while many people are interested in performance of much heavier & texture mapped games)
2)The drawing is done by the slowest possible way: immediate mode
3)Immediate mode is deprecated (and rarely used in any properly coded OpenGL game), so gfx card manufacturers don't bother optimizing it too much - it will never be as fast as VBO, so why bother? It's the fault of program to use wrong ways to draw.
4)At "too high" fps, any small thing can have big impact on framerate (say, drop from 4000 to 3000 fps) which in most cases doesn't mean that 40fps game would slow down to 30fps.
5)If you have "sync to vblanc" enabled, fps will be dropped dramatically (to actual screen refresh rate) - which some might interpret as "something being seriously wrong with drivers"

At least, please don't call it benchmarking

@kas1e

I confirmed you issue on LodePaint, it freeze on my Sam too, maybe m3x remove somethings when trying to increase the performance ... and yes it is only 1 or 2 FPS more, i think we need to wait the next OS update (Warp3D) for other little improvement, (bug fixed mostly) and then Mesa/Gallium

The most important for end users results (does not matter how call it), are in actual apps and games. And games and apps, show for us 1-2 fps difference + some new bugs. Of course you can be pedantic and show us how good you understand all that stuff, but for end users all of this more than enough.
