Are you possibly using Windows 7 with Aero disabled?
If you're considering BFGX, remind your 4350 doesn't support D3D 11.
Anyway, you don't want to use bgfx. You want to stick to D3D9ex and solve the resolution issue (i.e. borders) you mention in one of your many threads.
I'd start by trying -video vesa_768 instead of arcade_15, and if that doesn't fix the issue you'll need a custom preset (I can't help you with that atm since I'm away from home).
I am using windows 7 with Aero disabled why do you ask?
I am also using a PC VGA CRT so if you mean with CRT EmuDriver I'm currently using the Arcade 31.5kHz preset which was by suggestion by another user and gave me 640x480 on 320x240 games which is beautiful so idk which would be equivalent to vesa_768 for my monitor.
Also is it the 4350 that is causing both OpenGL and D3D11 to run at what the log says is 300% speed? I'm guessing there are bugs with the 4350 and d3d11 because dxdiag reports no issues with the video card and reports directx11 as what I have installed.
Thank you, I sware I'm doing my best to research and understand this just unfortunately to no avail. I've been doing nothing but work on this for 4 days and solving the resolution problem was more daunting then trying to slow this down as BGFX improved everything with one setting with a simple draw back that seemed solvable. I apologize if I'm doing things completely wrong but everything I read makes it sound like BGFX is better even the update logs for SuperRes.
