Help / Low framerate without 100% utilization
« on: August 31, 2012, 11:25:24 AM »
What happens: When I run blockland with shaders maxed out, my framerate in game is low even though my GPU nor CPU are running at 100% usage. I know its not a CPU bottleneck because the main thread blockland is running on is nowhere near using an entire core. Yes I am aware that blockland is not multithreaded and wont run on all 6 cores, but utilization is still less than one core can provide.
Here is a screenshot of what happens
You can see here that the framerate is topping out at ~31 FPS while GPU utilization is only reaching 80%
I did a little bit of looking into the problem myself and came across AMD's GPU Shaderbrown townyzer.
I don't have a lot of experience with graphics/shaders, but from my messing around with it I was only able to get blockland's GLSL shaders to compile and run with Catalyst 11.7, 11.8, and 11.9. If I try compiling on anything newer, it tells me "Hardware Compilation failed". The 11.9 version of the catalyst drivers are almost a year old at this point.
Computer Specs: AMD Phenom II x6 1100T, 16 Gb ram, AMD 5830 + Catalyst 12.8 Drivers, Windows 7 Ultimate 64 bit
