This isn’t the first time this issue has been noted.
Although the log doesn’t show it, I think BSNES may do some funky video things behind the scenes.
Are you using the stable or a beta BSNES?
In any case, my advice is to simply not use the most advanced preset and don’t stress about it.
awesome man. thx for the reply. i would sometimes check the log, and ive always kept bsnes at 1x res, and i would see the shader shooting up to a crazy resolution.
i think its the stable version. str8 up bsnes from the core list.
any suggestions for a snes shader to try out? thx
That is the issue I was referring to.
As far as a preset goes, it depends on what you want.
If smoothing is your goal you could try the \shaders_slang\bezel\Mega_Bezel\Presets\Base_CRT_Presets\MBZ__1__ADV__GDV-NTSC.slangp
BTW. I can personally load any preset with any variation of BSNES, so it may be a limitation of your GPU.
yea for sure the gpu isnt the best. i was just curious bc every other core could handle it but i get the gpu plays a role.
appreciate your feedback
Perhaps unrelated to this, but I was curious about the fact that there are two logs, on-board and GPU.
I personally think that if you are using a GPU, you should turn off the onboard unless you are using a dual display or other multi-monitor environment, because it is easier to have unexpected problems when two are running at the same time.
Even if all the other cores run, this could certainly be an issue for BSNES. I agree that it would be best to turn off the Intel iGPU in the bios.
Then there’s the electricity savings. 
FYI Near (creator of BSNES and Higan) said that SNES9x is perfectly accurate as far as they were concerned so I’d take that as an endorsement to use that unless you have a particular game that needs extreme accuracy.
is this something i’d do thru retroarch or in the actual bios of the laptop?
or is device manager disable a viable route?
It is certainly worth a shot. I’m not positive it would be invisible to software though.
Laptops can be weird. (Piping the dedicated GPU through the integrated.) It might not even be possible to disable the intel iGPU.
In the end, using snex9x might be the best advice. It is my go to core.
dope. appreciate all the info and thx for everybody else who gave some input.
The only downside to disabling the iGPU is that it might interfere with power savings. An alternative (in Windows 11) is to go to: Settings > Display > Graphics >
Browse and add Retroarch and select high performance; there should be an option to select the GPU.
iGPU is lower power and will help extend battery. 
I think of my power bills this winter and may have to just start accepting horrible game performance going forward. 
Just kidding… but yeah, snes9x.
Hello 
Where can I find the shader parameter for the background brightness of the game? I just want to adjust the lighting, nothing more…
Do you mean the lighting on the static background? Or do you mean brighten the game image?
“brighten the game image” 
This! but I don’t want to lighten it, I want to make it darker…
To do this you can adjust the post CRT brightness, or the Gamma Out, both of these are near the top of the parameter list
Does anyone know of a way to alter the bezel so I can hide the overscan on the left side of the screen? This is the Sega_MasterSystem.slangp shader. I know there are ways to hide it through core options but those compensate by slightly stretching the image horizontally and I’m trying to avoid that. Thanks!
Left side cropping is your only option in the shader.
Even if there were some other creative solution, anything that doesn’t stretch the screen would destroy the bezel’s relationship to the TV background.
Do you have the RA “Crop Overscan” setting enabled?
This usually fixes this on NES games. You didn’t specify which core you are using, but it may work.
TBH, since the aspect is set by the shader, even that would end up stretching the screen.
Hey guys… if I have, in my arcade presets, some colors that seem oversaturated and kind of bleed into the scanlines a bit, what is the best method to tone that down? I tried the saturation in the guest color parameters, but it didn’t seem to do quite what I expected. Are there any other parameters that would affect that specifically?
