Roblox Custom rendering frame?

Hello, I've built a ray tracing engine in Roblox. I'm using about 80,000 frames to display a 400 by 200 image using 1px by 1px frames. Roblox has a GUI object limit at about 85,000. I want to increase the resolution but I'm currently being limited by Roblox's GUI object limit. Is there any work arounds for this? I need pixel by pixel control and I'm not sure how to do this in a larger resolution. https://imgur.com/a/gFCCgBt I've tried to use an individual part for each pixel but that proved to be far too laggy. I'm looking for any ideas because I'm out of them. Thank you in advance!
