Yes, after escorting bombers from France to England. Once the enemy fighters left, so did the fps issue.

Same issue with me. Had that problem against AI fighters in a coop mission with 7 other Jg53 guys. We escorted a 27 Do17 formation, no problem. As soon as 6 hurricanes appeared: huge fps drop.

for me, when a FPS drop happens it's definitely on the second or third sortie, but this kind of degradation in performance comes from way back before the patch... at least now there's a minimum FPS cap, with higher settings, and it hasn't CTD yet...

before yesterday i attacked a formation of 4-5 Ju-88 in mid-channel, about 14000ft; they came with 1 escort 109, weaving over, i stalked from behind, gained a slight altitude advantage and pounced with impunity, after that run the Ju-88 i made a pass on went home smoking, with the 109 following him, i pursued them and soon there were 2 additional 109s in the vicinity, as i went after one a Spit came around... no FPS drop whatsoever

the same day, on a different session, about my third sortie, as soon as i got in the air there were about 6 fighters in a furball over Hawkinge, the FPS consistently dropped and stabilized on 15-10, then it got better as the situation cleared; i'm amazed it didn't CTD...

I suggest all of you who have this problem vote here http://www.il2bugtracker.com/issues/253 .

May I respectfully suggest that if you DON'T have this problem, the sensible thing to do is NOT TO VOTE - unlike some twerp I could mention (I had to restrain myself from asking my squad members to vote against his issues; a. I'm not that mean; b. he probably did it out of some degree of ignorance). The last thing we want is an issue that seems to be affecting a significant number of people (but a minority) to drop off this list of priorities.

Last night we flew a mission with 6 human piloted JU-88s on the ATAG server and when we were all lined up on the runway at Tramecourt I was only getting 4 fps. One pilot had a problem with his plane on takeoff and got separated from the pack, at this point my fps went up to and average of about 18 fps. As we flew over to England I held a frame rate that varied between 16-24 fps when over the water and it was just smooth enough to be manageable. As we approached target we all began our attack runs and as bombs were dropped on the radar station the crashes began; 4 players CTD at the exact same time and I, who was in the lead, was the only JU88 left flying. At this point when I had become the only player still flying my framerate went up to a steady 60 fps.

Aside from the CTD's it was a beautiful sight to see 5 88's flying in fomation with human pilots at the controls.

Voted...I had thought that I had skins disabled in game. I will have to see with it definitely off now, if I still have a problem on this server.

Fixed - for me
 

Thanks to Insuber's multiple suggestions, one of them seems to have worked.
I was too impatient to change one thing at a time, but either the skin downloads, or deleting my conf.ini seems to have fixed the problem.

Thanks. I'll leave this bug report up in case these changes don't fix it for others- at least for the moment.

P.S. I've just run a couple of sorties on ATAG, problem gone. I can also confirm that TSNotifier is not a cause.

Same here with the Br2o nose dive after switching positions, no problem with the alt 1-6 though.

The AI will take control on the ground when I switch positions sometimes:evil:

its really a gamebreaking problem??

Yes I do have these problems, no idea for a fix. You should ask mr Shevchenko.

But at least we can be sure that over a year after release, we have a new graphics engine, which makes the game perform worse once engaged in online combat, the paint job on my Spit looks like a child's drawing, the engine nacelles on my Blenheim are as blurred as, well....blurred; the rpm gauges are sometimes in focus but sometimes not. The few clouds we have appear or disappear at random in a sudden manner, we get a slideshow when we get on the tail of a 109, we blow up his fuel tank and he buggers off like nothing happened, and so it goes on.

But we hang on in there, waiting for the day when it'll all come right. And someday I'll be very, very rich. Honest.
