SFML is really slow on computer 1 but not computer 2
« on: August 02, 2015, 04:22:07 am »
As the topic say I have some strange problems with SFML. This problem is persistent on computer 1 with SFML 2.1, 2.2 and 2.3.

Computer 1 have a
AMD Athlon II X2 250 (3.00 GHz) CPU
8GB RAM
Win7 64-bit
ATI Radeon HD 4600 card

When compiling even the basic example that show the green circle the program will stutter, every ~1 second the window will "freeze" for a half a second.

Computer 2 that is a laptop with
Intel Celeron CPU N2830 (2.16GHz)
4GB Ram
Win8 64-bit
Intel HD Graphics with ~1.7GB total memory (according to DXDiag).

When I try the exact same code and executable on computer 2 there is no problem what so ever. So it doesn't seem to be a problem with the code since even the "hello world" SFML example is stuttering, so do anyone have any suggestion on what I can try to fix this problem?

Any chance the second computer is running without hardware acceleration? Any warnings in console with 2.3? Did you try other programs or games using OpenGL rendering?
