Can't you try another (proprietary) driver?

The open source driver is the official intel driver for linux, there is no proprietary driver, which is why I usually buy intel. Usually it works fairly well, but I don't do a lot of multimedia so I had never noticed this issue.

The computer is a Core 2 Duo P8400 with the associated integrated linux graphics. The driver is the intel open source driver which is pretty good by linux standards (which are pretty low :-().

I tried glxgears, and while it gives 60FPS (which is equal to the refresh rate, I think), it does have the same problem which is an occasion 200 or 300 ms freeze.

I guess this underlines the poor state of linux graphics, again. I hope wayland will sort things out. I'll try again with my desktop computers which has a newer intel cpu with a sandy bridge graphics chip and decent (in my recalling) graphics performance.

Anyways, thanks for your help, and have a nice week-end!

General / SFML lags on my computer

Hi all,

I have started writing a few simple things with SFML and so far I love it, the API is great!

Unfortunately I've found out that even simple animations lag on my computer. At first I thought it was a problem with my code, but the pong example provided with the library lags as well. The animation is pretty smooth, but every second or so the is a big annoying lag. I can probably film my screen if needed.

My computer runs 32 bit Arch Linux with open-source intel graphics. I can run games such as supertuxcart or play movies, making me think it should be able to handle a 2d ball game. I checked and SFML seems to be built in Release mode.

What could cause this problem? Are other people experiencing it as well? Thanks!
