This patch resulted in a significant improvement of the Framerates in my case. The game became totally playable at high settings and
smooth at medium settings as enumerated below (video Settings). I can now enjoy the stunning details of IL2 COD

Roughly speaking I think the patch easely doubled the Framerates!

At the moment I'm enjoying the sim to much to give a more pertinent bug report but here is 1 small typo and a little bug I came across 10 minutes ago (a futilities really):
1)
- In the French version of the game when you land and brake (using default B key for example) it says:
"Freinage des routes: Activé" "Freinage des routes: Désactivé"
- The message corrected would be:
"Freinage des roues: Activé" "Freinage des roues: Désactivé" (routes = roads | roues = wheels)
2)
- I crashed with a Spitfire, a wing broke off but there was no sound at all when it happened.
Anyway, in my opinion IL2 COD is a beautifull baby trying to make it's first steps. I'm sure it will grow stronger and become a Greek hero
Keep up the great work IL2 Devs !
