Hrm... so I need to update that claim a bit.
I tested it on a Dell Inspiron 1440:
Win7 64-bit
Intel Pentium T4400 / 2.2 GHz
4GB of RAM
Cruddy Intelgrated GPU 4 series.
Now, with one entire Sath visible on screen, retail actually outperforms:
Retail: 36fps average.
HTL: 22fps
Here's the magic: Up close, as in destroying turrets, flying over, or goofing off:
Retail: 40fps average
HTL: 56fps average.
With 12 Saths on screen:
Retail: 9fps Average
HTL: 13fps average
There you have it, folks. That is with 3 4096^2 textures, each with a glow and normal. Imagine the performance when I release a 'lite' version with 2048^2 textures. Excellent work and hats off to the optimizations the SCP team have integrated.
