Title: Question about sprite/rectangle shape performance
Post by: EvOlLuTiOn on April 05, 2014, 10:05:26 pm

Hi,

while working on my game i noticed this. It looks like sprite gives better performance than rectangle shape.

Here is link to my example app https://dl.dropboxusercontent.com/u/21883169/Release.rar (https://dl.dropboxusercontent.com/u/21883169/Release.rar)

When using sprites i'm getting stable 80 FPS, but with rectangle shapes it's only 20 FPS. I mean shouldn't be performance with shapes better? Four times slower is a lot actually. Code for booth ways is almost identical.

I know that you can use vertex array, but i'm just curious about sprites/shapes overall performance (attached application is just demonstrational).

My second question is: Is it known fact that ATI GPU + AMD/INTEL CPU gives better performance in SFML than NVIDIA GPU + AMD/INTEL CPU?

Sprites are optimized, otherwise this class would not exist and everybody would happily use rectangle shapes everywhere. So don't be surprised.

No. But unless you tested many different configurations that use this pairs, I don't know how you could say that. It's just one (or a few) machines compared to one (or a few) other. And of course performances are different because every machine is different.
