Nintendo 64 Visual Issues

I'm new to the Nintendo 64 core on Mister, so forgiven me of this had been addressed.

I recently got a Superststion and was trying to play Goldeneye 007 on the N64 core, however the visuals are terrible.

I tried every setting I could to try and improve things, but everything appears to be a blurry mess.

For example on the main save selection screen, Bond's profile picture can barely be made out. If I select HDMI display mode it does improve, but not by much.

Any help is appreciated. Playing via hdmi on a 4k TV. (I know this is impactful, but not to this degree, all other systems look fantastic.)

I can provide pictures later if it helps.
