CPU Multithreading please.

hi,
here are some test I've done looking to understand what influences the IL2 COD performances:

These are the commons options for all test:

notes:
- The HD6950 is a 2GB version tweaked up to a HD6970
- The CPU is aircooled with an A70 Corsair (hardly fitted into the cabinet )
- DDR3 16GB Vengeance 1600Mhz
- no windows paging file
- Game loaded onto a 6GB ramdisk to slowdown the game loading times and the missions loading times (and ingame objects during the fly)
- Test made playing the "Black Death" Track and using the FPS SHOW START internal option
- Radio voice comunication OFF in audio menu settings

- Common game settings:

overclock 1:

this test seems to show that cpu overclock benefits ingame fps

overclock 2:

this test seems to comfirm the previus one and show how heavy is the shadows option

GPU overclock:

this one should show that GPU overclock doesn't help (???!)

affinity:

assigning processes to one, two, theree, four and six cores...
- See that starting from 2 cores and up, launcher.exe doesn't change performances.
- The best system seems to be a dual core processor that gets best results for FPS min.
- A one core CPU isn't able to play as the others

other settings:

you can't see here performance changes working on minor settings or trying to use priority process assignements

power boost:

By desigabri at 2011-11-12
same conclusion for catalyst boost settings

very low:

By desigabri at 2011-11-12
very low settings helps a lot for FPS results, anyway you can see that "effects" are very heavy here, also if setted to MEDIUM for FPS min

repeatable:

By desigabri at 2011-11-12
the last comparision is made only to see that comparing test made in different times but having the same options, get same results.

Before this test I believed it is more important the GPU overclok then the CPU overclock (for ArmA2 I got that conclusion). For IL2 CoD seems the opposite.

code still needs a lot of attension for performance

sure they are hard at work for a big frame rate performance boost.
