choppy?

[adrix89]

It seems all of the demos I have tried lags the frame at 1 second intervals
Its not the framerate it looks more like a function that is called every second
Anybody know anything about this?
I'm using the windows xp, ati radeon x1900 and an old single core amd athalon processor

I've had this problem with XP on old graphics cards before.
I can't tell you why it happens, I ish no windows expert.

Edit: Maybe you should check your drivers.

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/malware free, and it's not affecting any other games/applications.

It's such an irritating glitch that I physically cannot stand to look at it for more than a minute without getting dizzy.

It runs like a charm on my partner's PC, which is considerably lower spec, and has a builtin Intel graphics chipset.

...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.

So you're saying that ATI has glitches? Most of the computers in mah house have AMD processors, and most have ATI graphics cards... It's only happened to me on XP.

My apologies- noted for future ref.

No I'm not - I've had no such issues with anything else that uses SDL for rendering, windowed or full screen. So this issue appears to be specific to something LOVE does while in windowed mode- not my graphics card or OS.

Well, it has to be that as well, since other people don't have this problem with LÖVE as well. I don't have the problem, ATI or otherwise.

Well, there are at least two of us who do.

[Robin]

Exactly. So, what do you have in common which no-one else has?

It's not that I'm running Windows XP, because it runs fine on another machine which also runs XP.
It's not that I have an ATI card, because you stated you don't have a problem with ATI cards.

Beyond that- I don't know.
