Hey guys,

I play at 2560x1080

Recently what happens is that the sides of my display start showing artifacts and lines from the minimap.

Sometimes when I use advanced zoom, the game "renders twice" on the sides when i zoom out.

Changing resolution and other display options doesn't matter. Usually is this happens mid-game I switch to 1920x1080 to get rid of it, but on an ultrawide display it looks stretched.

Anyone else have this bug?

I am playing at 3440x1440 roughly 21:9 and I don't have these problems.
Maybe try to play around with FOV and switch between fullscreen / windowed modes. I use a FOV of 75 and Full Windowed.

Also if you find more problems with other apps you might want to see if something with your graphic cards is wrong. I once had artifacts shortly before my old graphic cards broke down.

I've had some issues with my AMD card before. Messed around with settings in the graphics card options, seemed to fix it. Also, outdated drivers really make a difference.

i run at 2560x1080p aswell, i don't have any artifacts.
how are your gpu temps ? drivers up to date ? etc.

Problem still exist i got monitor 34"Ultra Wide 1440p play 2560x1080 Card AMD Rx6700xt when Use Adv.zoom [color=#959595]the game "renders twice" on the sides when i zoom out.[/color]

game doesn't handle 4k very well either. though im not against dropping res if i have a lot of work to do in the mech lab.

though the glitches you describe sound like bad shaders, so try flushing the shader cache in the repair tool and see if that helps.

I've tried gtx 1660Super and it worked fine so the problem only happens on AMD GPUs, at least on mine RX6700XT

I've found a few people around the internet with all sorts of these graphical glitches from that card series. But there was a reply on this thread that really stuck with me.

Workgroup / Precision Errors in the Shaders cause this... and is why you DO NOT Develop exclusively on NVIDIA Hardware.

A common issue is Developers don't account for how AMD Architecture works., or more specifically how the API Specification is SUPPOSED to work... and instead they develop based upon how things work on NVIDIA Hardware. What's likely happening is that they're constructing the Reflection in 8x8 or 16x16 "Blocks"., almost certainly as the Console version uses Chequerboard / Tiled Rendering; this means that the Data for the next Pass should be shared, but the Specification itself means that the Hardware will by default flush (reuse) said Memory Space ... thus you'll get Garbage Data out, as it's no longer the actual data you held there.

NVIDIA won't actually flush memory until it runs out and needs to allocate new memory.

As a Developer you're supposed to always assume an area has flushed and store reusable data in a non-volatile cache., but as noted lazy / bad developers who exclusively develop and test on just NVIDIA Architecture will simply assume if it works a given way on NVIDIA it'll work the same on all; when the reality is NVIDIA isn't working as the Specification Dictates.

Thus the result is artefacts on AMD Hardware., you'll commonly see this in Chequerboard Render Games with Reflections and/or Shadows; and it's a BAD habit for the Developers. The Frostbite 2 Engine (for example) also suffers from this issue in many games made with it; although not with the base version that DICE themselves put out; as they do develop with AMD Hardware.

Remember, MWO was originally developed for NVidia. If you scroll down far enough, you'll still see the NVidia logo right beside the PGI logo at the very bottom of the page.

1440p and no issues here either. Perhaps it's the specifics of 2560 x 1080 as there doesn't seem to be an issue with 2560 X 1440.

Ahhh, and using RTX 3080 card, so this might help as well.
