Refresh rate probs in windowed mode (!)

Recommended Posts

Because of a performance problem in a highly-graphical app that I''ve been working on in my day-job, I''ve been getting my feet wet with DirectX (7 for the moment). I''ve never had much problems with it when I used to use it, and we''ve used DirectDraw in the project with no problems. However, when it comes to creating a windowed app that uses Direct3D, I get the following weird behaviour: Setting anything but a software-emulation mode causes the refreshrate to drop to 50 or 60Hz! This is VERY annoying and headache-inducing. I''m running it on a GeForce2 GTS, and my standard desktop is running at 75Hz. Starting up the (windowed!) app, causes it to drop lower immediately when the Direct3D device is created. I thought windowed apps COULDN''T change the refresh rate, this is puzzling me. Has anyone seen/solved this problem? People might not remember what you said, or what you did, but they will always remember how you made them feel. Mad Keith the V.
