There is a persistent issue with LOVE and vsync on certain hardware/driver combinations. Try setting vsync to off in the affect LOVE program by doing this: Add a file to the program's directory called "conf.lua", or use the existing conf.lua, then put this inside the file: function love.c...

Mm I'm no windows expert, but are you certain that your machine is malware-free? Explorer.exe slowing down things is a bit suspicious. 99.9% certain- I've just finished up an extensive clean-up & patch run. It's been behaving this way for me since I first tried LOVE out a few months back, and t...

I went with the trial and error approach to see if it was a process on my machine, and it looks like it's explorer.exe (even with no open windows, only the taskbar, I don't have any fancy reskinning stuff going on). Even if I'm running a ton of other processor intensive stuff at the same time, the p...

Yep, no issues with OpenGL in anything else.

I give up.

...In addition, it doesn't seem to be a problem when switched to fullscreen mode, even at my full desktop res. Double poster! Bartbes, yell at him. :P My apologies- noted for future ref. It runs like a charm on my partner's PC, which is considerably lower spec, and has a builtin Intel graphics chip...

I get the exact same problem (jumping once every second like there's something processor intensive happening every tick, happens on all demos), my drivers are up to date... I'm on a dual core 2.8Ghz with 4Gb of RAM, and an ATI HD 4600. I've shut down any other programs I had running, I'm virus/malwa...
