Textures bugging on Call of Duty 1 (OpenGL)

Hello.
This is a longshot considering how old this game is but I'm having really annoying issues with the textures in CoD1 since I have my new PC (with a rtx2080).



As you can see on this first screen walls are fine but the snow is messing up.

And here on this one it's the opposite, ground looks how its supposed to be but the walls dont.

I have tried every possible settings on the nvidia control panel and a few on nvidia inspector, but this issue doesnt go away. Half the textures in my game have that blurry effect and it annoys the hell out of me.

If anyone has a clue how I could fix it and enjoy good graphics please help me.

Thanks.

 

set nvidia filtering quality to performance or quality, not high performance.

 

it's on high quality atm but as i stated i already tried every CP setting. allowing negative lod doesnt help either.

 

I said Quality, not High Quality.

 

I know but I already tried it and it doesn't make a difference so I stick with high quality
