it's still a beautiful work .... i just need better hardware

No. Neither it is a beautiful work or you need a better hardware.
People from aerobatic teams asked me about this mod and his compatibility and other... because P-51 is the most popular team aerobatic plane in Il-2. So I have checked the mod, rather deeply. So, in my opinion, that is the way in which mods should not be produced. I don't write about minor bugs, but there are many major mistakes: starting from the project and ending with the realization.
The amount of additional meshes and textures do not represent the size of improvements. Many textures are oversized. Most of textures resolution have been multiplied by factor of 2 (or 4) than default one, but the have not been repainted from scratch, but the "sharpen" tool was used in connection with making textures more contrastive. This is a waste of memory, because this way you can't improve texture quality.
Men who prepared this cockpit put some work with it - I agree. But in my honest opinion: if you do something you should do it correctly and well up to the end. I think that it would be much better for all of us if the author, instead of adding not necessary meshes, just repaints default textures with improving their resolution by the factor of 2.
So, yesterday, with being angry on fact, that this cockpit is absolutely unusable, I started preparing my repaint. Painting each element from scratch. I can show you a comparison of two elements marked with red on pictures below. The first shot is from default game (texture 256x256), the second was done with the mod (texture 512x512), and the last is done with my repaint (texture 512x512):


The textures used in that shots: (remember, that the one which is mine is not completed - I just did that two parts):


I am not a texture master. I can't paint well.
But when writing "oh!" and "ah, what a beautiful cockpit!", please, keep in mind, that in the most important parts, the author did almost nothing more than resizing and applying contrast filters.
