I develop a test application with directx 11 und fl 10.1. Everything is working as expected and fine, but when I maximize the window with my graphics in it, the time per frame increases drastically. like 1ms to 40ms. If it stays at a lower resolution range, it works perfectly. But i need to support it in the maximized resolution also.
Destination hardware and software specs:
- NVS 300 graphics card
- Windows 7 32-bit
- resolution 1920x1080
- Application that draws few sinuses with direct3d, c# via sharpdx
- Windows forms with a control and sharpdx initialized swapchain, programmed to change backbuffer on resize event (would occur without that too though)
- I used a System.Stopwatch to find the issue at the code line: mSwapChain.Present(1, PresentFlags.None); where the time it needs when maximized increases by a lot suddenly.
If i drag and resize it manually at some resolution the frame time jumps, seems weird.
If i comment out the drawing code, I get the same behavior. On my local development machine with a HD4400 i don't have this issue though, there it works and the frame time isn't affected by resizing at all.
Any help is appreciated !
I am farily new to programming in c#, windows and with DirectX also, so please be kind
First instinct is to simply blame that hardware.
