so I downloaded the GLSL shader mod and then downloaded the Mr.meep's 3'x shaders and was completely running it fine on my server, had the same fps i usually do (60fps)
played for about 5 min and all of a sudden, no build up or anything, it started lagging SUPPER hard and i was getting 1fps so I checked task manager and both the java processes (my server and I think the game) were taking up almost 50% of my cpu each
i exited of of both of them but they were still taking up close to half of my cpu so i ended the processes through task manager and I was back to only 5% of my cpu being used.
started up minecraft and my server again and was running fine with the same shader for about another 5 min and the same thing happened
so if anyone know what happened or if there is a possible fix please let me know because I like that shader
