Direct 3D issue

[Sam_Dillard]

Okay so... In windowed mode, Direct3D 8 + vsync = 60fps (the correct framerate in this case). Direct3D 9 + vsync drops to 50fps... however in fullscreen mode goes up to 60fps...

Am I missing something here? Yes all drivers are current and etc. I don't understand why D3D8 has constant framerate but D3D9 has problems in windowed mode but none in fullscreen... Strange.

And what are results without V-Sync?

[Bruto]

wait, V-Sync isn't supposed to run with DirectX thing.. and completely unnecessary with the new Direct3D hardware acceleration?

[Looki]

Bruto, what? Why would V-Sync be unnecessary? It's used in all of today's 3d games.

[Sam_Dillard]

Without v-sync D3D9 goes back to 60. So... (Windowed+vsync)D3D8=60fps, >>D3D9=50fps
(Fullscreen+vsync)D3D8=60fps, D3D9=60fps
Without v-sync everything is 60fps...

[Fanotherpg]

So here's answer. V-sync works with refresh rate of your screen ao it is bot save to use it (different refresh rates in different countries and on different screens)

[Sam_Dillard]

Yeah I know how v-sync works, but the screen is at 60hz and vsync with D3D8 works normally, D3D9 however loses 10fps in windowed mode, but not in fullscreen mode.

unless I did not read correctly, I remember Yves or François saying something like that, about the Vsync being used with the old DirectX option.

The window app using dx9 might use a bit different rendering then fullscreen one. Cause gfx also renders screen around window. And what happens after maximizing window?

[Sam_Dillard]

Maximizing the window is the same as windowed mode for D3D9- fps fluctuates between 50-60fps (with vsync). D3D8 remains consistent 60fps the whole time. I am using Windows 7 64bit, if that makes any difference. It seems that when using my old Vista computer, this problem never happened. So I don't know if it is due to the OS, or perhaps the latest version of hwa...?
