Title: Low FPS
Post by: fer_t on August 08, 2012, 03:18:01 am

Hello,
I hope I am in the right sub-forum ;)
I have a problem: Low FPS.
So also if I only have a main-loop with clock.restart, window.clear and window.display, I only get 50-70 FPS, but I expected more then 500-1000.
I do not think it is  a hardware problem, I have a AMD Phenom II x3 (3x3,0Ghz), 4GB RAM and a MSI HD5770 Hawk graphic card so I think this should be enough ;)
I use openSUSE 12.1 64Bit with SFML 2 (build from latest source code).
Does anybody have an explanation? It really confuses me ;)
Thank you :D
BR,
fer_t

Is framerate limiting enabled? Is vertical sync enabled?

Even if v-sync is not enabled in your program, it may be forced by your driver.

No FramerateLimit and V-Sync are not enabled.
But Laurent, you can be right... I am using X.Org Gallium 0.4 (radeon driver). So I think I test is again with the original proprietary ATI/AMD driver.
Thank you!
