Hardware Based XRender Slower than Software Rendering?

Neon Spiral Injector writes "Rasterman of Enlightenment fame has finally updated the news page of his personal site. It seems that the behind the scenes work for E is coming along. He is investigating rendering backends for Evas. The default backend is a software renderer written by Raster. Trying to gain a little more speed he ported it to the XRender extension, only to find that it became 20-50 times slower on his NVidia card. He has placed some sample code on this same news page for people to try, and see if this is also experienced on other setups."

are the drivers installed?

last time I checked all graphix cards need drivers to enable their acceleration.

It may be big and bloated, but at least it's slow.

Works nice and fast for me

After installing imlib2, and running render_bench's 'make', it gives me the following:

cc -g -I/usr/X11R6/include `imlib2-config --cflags` -c main.c -o main.o
main.c: In function `xrender_surf_new':
main.c:67: `PictStandardARGB32' undeclared (first use in this function)
main.c:67: (Each undeclared identifier is reported only once
main.c:67: for each function it appears in.)

It seems to do this at the same speed, whether or not I have render acceleration enabled.

Re:Can you learn to spell?

[efishta]

needless to say most english speaking people know that the "x" letter is pronounced the same way as "cs" or "ks"... so I figured it would be redundant to type to letters when I could very easily do half the work and type one letter.

Replying to this post completely negates what I was trying to accomplish with my "x" trick, but I thought you'd like to know.

It's just like my uncle Fortranna Rosanadanna used to tell me. It's always something. Either your XRENDER is slow or you're stuck with a two bit disk drive.

Back to you, Jane.

Yup. And of course XRender knows that, and has decided to punish him.

Re:Rendering backends for Evas???

I'm not sure if you've heard of them, but worldwide there are a hundreds of thousands of women called Eva. The most famous would probably be Eva Peron and Eva Braun.
