Too slow 2D

[GRAVITY]

Hello everyone!
I just recently started to use IrrLicht

I decided to experiment with 2D graphics. upload picture "demoback.jpg" from the folder "media". well, and rendered them in the loop 4 times. draw the same cursor-image.

when drawing visible plume from the cursor x_x.
Surely such a small speed of rendering in 2D IrrLicht?

I work in ubuntu9.10, using code blocks.
video card - gf9500gt, 2 gigabytes of RAM, intel dual core 3GHz.

sorry for my bad english

[sudi]

what?
show some code please

Try changing antialiasing to 0 and see if speed increases.

[GRAVITY]

speed has not increased

Code: Select all

dimension2d<u32>(1280, 1024)

Are you sure your graphic card supports this strange resolution? Maybe try a more common one.

Code: Select all

device = dimension2d<u32>(1280, 1024)

That's not a strange resolution That's a common 4:3 19" display

Oh, sorry, my bad. Just misread it. I run the same resolution.

Using the 2dmaterial settings has some performance problem. However, I don't know how much performance drop "visible plume" means. Some numbers about FPS would help more.

[GRAVITY]

only 19 FPS.

Another such moment .. I use the built-in video driver. hmm ... perhaps this is the reason for such a low fps
I'll try to setup nvidia drivers, and then report the results!

Thanks for the answers!)

Replace "perhaps" with "for sure".

[GRAVITY]

exactly))

I did not think that the built-in drivers such slow)
Now I was convinced

FPF risen to 400)

[hybrid]

Well built-in driver is probably the wrong term. It's a software renderer, which means no hardware acceleration.

[GRAVITY]

Thanks for the explanation.

I have another question:
I have image size 1000x1000. And i want draw this in another resolution - 500x500. How can I scale this?

Thanks a lot.

Help ))
