Disabling Synchronize refresh drops framerate over time

[Antipalad]

<p>Disabling Synchronize refresh while in windowed mode drops framerate on my computer to under half of what it should be after about an hours playtime.</p><p>Areas where I get around 110 frames per second in semi low settings drop to 44ish and when moving, it feels like fps is around 20ish with visible skipping.</p><p>Computer is a e8400 at stock clock with 4gb ram, and a ATI radeon HD 4850 1gb graphics card. (latest drivers, windows 7 ultimate, all up to date)</p><p>Works fine if I have vsync enabled, only occurs when I turn it off.</p><p>Edit to add: Figured out this was the ingame browser minimized that ruined the performance.</p>
