Issue with getting GZDoom to work properly

[binklefish]

This might end up being a dumb question, but I recently downloaded GZDoom so that I can try out something I learned that requires it. When I loaded my map to see what it was like, there were several issues that made it very difficult to play it. I messed around in the settings and kind of fixed some of them, but there's still some things bothering me.

 

Firstly, when I had opened GZDoom for the first time, everything looked extremely distorted and it was all a mess stretched pixels. I eventually set the scale factor to its max, and set the resolution scale to custom. This makes the screen kind of stretched vertically, but it looks normal now. So, if I just have to deal with this slightly stretched view, that's fine.

 

The main issue I have is how every time I load a map, I'm able to look freely up and down, and this causes everything to be warped and overall displeasing to look at. When I first started GZDoom (after fixing the first issue), I went into settings to change the render mode from "hardware accelerated" to "doom software renderer" because I didn't like how blurry everything looked. What I didn't realize was that this caused the free look issue. I tried disabling free look in the settings, but every time I load a map again, it enables it by default. I couldn't figure out how to stop that from happening, so I searched some potential solutions to this, and found out that it is possible to disable free look in a MAPINFO lump. When I did this however, everything became slower and much less smooth. I don't know how else to fix this.

 

And lastly, when I try to pause my game and search the settings, all the letters on screen keep flickering. Sometimes there are long, black lines (kind of like thin triangles) that stretch across the screen and flicker too. This is annoying and it makes switching different settings difficult. This also seems to happen randomly, with varying severity. I could load a map with GZDoom and everything is fine, then try again and have it start doing this. This also happens with the HUD bar, and it usually happens when picking up an item. 

 

Did I set up GZDoom wrong? I really want to be able to do what I was originally planning to do, but right now it's very difficult to do anything like this.

For fixing the "blurriness", go to Options -> Display Options and set "Texture filter mode" to one of the "None" options (I use "None (linear mipmap)" myself; the various Nones all have different behavior on how textures on distant scenery look, just pick one that suits your eye best).

 

For the rest of it, check that your graphics drivers out of date. That sort of glitchiness seems like something screwy with your drivers/GPU.

I set the texture filter mode to none and it worked, but the main problem now is that free look is enabled even when I switch back to "hardware accelerated".  This wasn't happening before I disabled free look in SLADE. I deleted what I wrote in the MAPINFO lump because I thought I wouldn't need it anymore, and the game ran smoother without it before. Now, free look is still on by default, and the game still feels really rough. 

 

And I actually do think it might be something with my computer like you mentioned, although if it is then I know nothing about computers. I don't know if this makes me stupid, but I'm not sure how I'd check my graphics drivers or other stuff like that. I know I'll have to look into that on my own, so for now, thanks for helping me out.

Hey, so I messed around in the settings more, I really don't know what I did but it runs smoothly now. I added back the free look disable in MAPINFO, so I think that's gonna be a little annoying to add to every map I make, but other than that all my problems seem to have been fixed. The resolution is good, the free look issue is taken care of, and my menu doesn't glitch around. 

 

And again, thanks for helping me with my question!
