the game unturned is running with low fps. I have a late 2011 MacBook pro. 2.4ghz cpu i5.
intel hd 3000, 512mb. with bloom and light shafts I'm getting about 29fps. when I turn up the detail distance it drops to 6fps. clearly 2.4ghz is fast enough not to do this.

Short answer: this is expected — the limitation is the Intel HD 3000 (integrated graphics), not the 2.4 GHz CPU. and were right to point at the GPU. Increasing detail distance multiplies the number of objects, triangles and textures the GPU must render; enabling bloom and light shafts adds expensive post‑processing passes. On a 2011-era integrated GPU with a 512 MB framebuffer and shared system memory, those workloads can quickly exhaust graphics memory and push the GPU into heavy shader and memory thrashing, producing the large FPS drop observed.

Practical, immediate steps that improve frame rates:

  • Lower the detail/draw‑distance slider and keep it well under max.
  • Turn off bloom, light shafts, shadows and any ambient occlusion/post‑processing.
  • Reduce resolution or use a render/resolution scale (lowering internal resolution helps fill‑rate and shader cost).
  • Set texture quality and object detail to Low; disable anti‑aliasing.
  • Close background apps and browser tabs (they compete for memory and CPU cycles).
  • If the Mac has dual GPUs (some 15" models do), force the game to use the discrete GPU via Energy Saver/graphics switching or a GPU‑switch utility.
  • Monitor CPU vs GPU load (Activity Monitor or a simple profiler): if CPU is low and GPU pegged, the bottleneck is the GPU.

Longer term: playable high detail requires a discrete GPU. For consistent high detail and draw‑distance, consider a newer machine or one with a dedicated graphics card. The observed behavior (29 fps with some post‑effects, 6 fps when draw distance is maxed) matches how integrated GPUs behave when their memory and shader budgets are exceeded.

Let's read a bit about the Intel HD 3000 test results. http://www.notebookcheck.net/Intel-HD-Graphics-3000.37948.0.html shows a sea of red with many zeros and single digit results. What made you think this graphics solution was better?

It's not the CPU at issue here, it's the graphics solution (which is, well, how to write nice here?)

What is this 512MB? Directions unclear. If system RAM, you must be a very patient person.

Yes. Its your graphics hardware, not the CPUs. A 2.4 i5 will be perfectly adequate with a decent graphics card. One of my machines has HD3000 graphics. Its fine for ordinary "business" use, but hopeless for real-time 3d games.

my system has 8gb ram. i have got the latest intel hd graphics drivers but its still not working

. I supplied examples of the framerates you are seeing. It looks to me it's working as expected.
