Aircraft performance fall off with Win 7? last call for explanation

[SaQSoN]

Check your joystick settings and calibration. This is the only thing, that may change together with OS change.

An OS change isn't going to have any effect on the flight models so basically the only thing that it could be, as SaQSoN points out, is input related.

Do you still have Windows XP available to you (i.e. is it an old system). Why not do a test run with a stop watch and see how long it takes for the Corsair to accelerate to top speed at sea level using the same testing methodology. Between the top speed reached and the time it takes to get there should give you an indication on if there is an actual change or not. It may also help zero in on what exactly appears to be different...again something as simple as the joystick sensitivity settings requiring an adjustment may be it.

Windows 8 the corsair is faster

Seriously though..........

As already said it can only be the settings in your IL2 thats different or incorrectly patched/corrupted version.

I'm not sure how the physics are modeled but you might find that your new CPU/GPU has more 'maths options' (MMX/XMM/SSEx and whatever's on the GPU) to choose from, as compared to XP on the older laptop.

If the game is using these options for physics calculations, and its different to what it was on your old XP laptop.. the results will be different. What you getting now is probably what the devs intended the physics to be like.

A slight adjustment in your flying skills would help you re-enjoy the game again.

The physics might be calculated faster leading to faster frame rates only. You can't take shortcuts here with a slower or faster CPU... otherwise multiplayer would be a write-off. So no... not likely to be the case.

Some games benefit from having the extra GPU backing to produce visual effects related to physics (i.e. StarCraft II will show more debris being tossed around and interacting with the environment) but the gameplay physics have to be absolutely, 100%, identical. I'm not sure if there is a margin of error here but it would have to be small.

Maybe a very stupid question, if so I apologize.
Are you really sure, you installed the same version of the game (patch) in XP and in Win7?

[Pugo3]

I installed 4.07 from the same install DVD for both computers, and after some time finally patched my later Win 7 set up up to 4.10.1. Being that I noticed the drop off early on while in the familiar 4.07, it doesn't appear to be a error or corrupt install, but thank you.

There is a difference between the different maths units on the processor. Intel documents this (1000s of pages). if IL2 chooses FPU/GPU on an XP laptop, and MMX/XMM/SEEx on the new laptop, the results depend on the Options used for each maths unit.

I doubt whether UBI or TD have worked on this yet, with regard to C or C++ compilers as these are not the best solutions, other than absolute control of your compilation process - not offered with C or C++ compilers as of yet.

Guys, I think Pugo3 is comparing V4.07 with V4.10.1, yes there will be a rather pronounced change in the way that aircraft behave if that is the case.

Pugo, on the deck dogfighting a Ki 43 with a much heavier Corsair is a formula for failure.

Way beyound my understanding, but basically that different processors can produce different flight interpretations?
