Low framerate without 100% utilization

[Starcraftman]

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.

Is that Windows 7? I think what your experiencing is normal, I had a GTX 550ti and I used to get 100fps now it's a lot lower. I remember reading where I think Badspot or kompressor explained how many FPS you will get with the update.

Idk what else to say

My 2 cents.

Blockland detects that it doesn't need much more than %8 percent of your processor to run. So it only uses what it needs but it's actually needs much more than that. Same with your GPU

Is there some sort of way to tell Blockland to run GPU and CPU at %100? That would be great because this is also happening for me and I have no clue how to fix it...

After a bit of messing around I found that putting blockland into fullscreen mode nearly doubles my framerate for some reason.

fullscreen always increases performance in any application.
