Scanlines when using what video mode?

We could use exact steps or more information to reproduce what you're seeing on your end.

What exact parameters are you sending to mame64?

I modified resolution line on mame.ini. There are blurry scanlines without selecting em on the Mame's menu with 1600x1024@85. If i put resolution higher than this (like 3200x2048@85 ) there are scanlines inside the game.

It can be any resolution that is higher than 1600x1200@85.

is this actual scanlines, or interlaceing lines because some part of your hardware can't display that resolution in progressive mode and switches to interlace?

it really sounds like a hardware problem.

I don't know many about such things. I think when resolution is not available the menu returns to 640x480 85 hz which haves scanlines and game returns to 1600x1200 75 hz (my hardware is not support 1600x1200 85 hz but supports 1600x1200 75 hz).. That resolution is what shows the monitor when i open its menu. It happens with other
resolutions which are not available also.

How can i capture video or screenshot in Mame menu and inside a game? Pressing F12 or PrintScreen button inside mame menu or inside a game i get a black image
when i paste it to drawing app. Taking screenshot with mobile is not okay as it will be not very crisp enough to show the scanlines as capture with pc.

I have posted the screenshots using a cell phone when has scanlines. Are the last two above. Enlarge the images or make them smaller with a graphics program
that supports zoom.

When playing gameplay speed is 100 % ? You has tried with anothers games ? The issue happen with vertical games ?
Just for test try in Nvidia Control Panel disable antialiasing, triple buffering, vsync and other options.
Nvidia not is updating drivers for 8000 series. You are using the latest driver for GF8500 GT ?
I had a Radeon HD 3450 and HD 3300. MAME run slow when using high resolutions using both GPUs and GF8500 is more fast.
The scanlines not look to be problem in video card.

When playing the gameplay speed is 100%. I tried with other games and the problem exists with em also. It happens with both vertical and horizontal games.
I have disabed the options you said in the Nvidia Control Panel but didn't helped. I'm using the latest driver for my graphic card GF8500 GT.

The version of Nvidia driver i have is 342.01 (i'm not using MSI Nvidia graphic driver but Nvidia general driver). Unfortunately i can't test mainboard's Intel integrated graphic system
because Mame does not starts at all with it. It only has 256mb of ram so may be this the reason.

GPU 256 MB is enough to start MAME using that resolution.
Try using BGFX D3D9.

I have succeeded to test it. Scanlines don't appear with the integrated motherboard's graphics system using BGFX D3D9 with that resolution or other resolution.
