Default Massive memory leaks are still in the game code!

There are several major bugs that have been around since the release of the game, and this is still one of them.

Originally, this would most quickly occur when you flew near a formation of 3+ 2 engine German (player) bombers. Don't ask me why it didn't affect the Blenhiem, but it just didn't. It only affected the Ju88, Bf110, and He111 (I didn't have the opportunity to fly the BR20 in formation enough to know if it affected it or not). This would also occur in dogfights with 4-5 player flown single-seat planes, but it didn't always happen.

At any rate, the game would slowly drop FPS until the game slowed to a .000001 fps and then the game would crash and we would get a launcher.exe error in windows.

About 3 or 4 patches ago, this was changed. Now we do not get the launcher.exe error, but if you try to fly a large bomber group, someone wil have an FPS drop below 1 fps and stays there. About 2 patches ago we tried this with a group of ~7 He111's and we lost about 3-4 players because of launcher crashes or FPS drops. Also, we still found this in dogfights with 4-5 planes.

Anyhow, the video below shows the same FPS drop I would normally get when flying in a tight bomber formation. There may have been a Ju88 in view distance, but I did not see it. I do know that there was a dogfight roughly 5-6km away from me when I filmed this video.

I only notice this type of bug in multiplayer, I have never been able to re-create it in singleplayer. I've also never noticed it when diving on AI controlled planes in multiplayer. I've attacked a formation of over 12 He111 AI planes with a steady ~40fps.

VIDEO:



-Another major bug that has been around since release is 'ghosts.' We believe it has something to do with de-spawning AI flights. When the game was first released, 'ghosts' were actually pilots/crew members sitting in mid -air where an AI flight had passed by. Now, there are no longer people sitting in mid air, but we still render the distance render dot of an object. When you approach this (what used to be an AI flight) there is nothing there. It is just a distance dot. When you get close, it disappears, but after you pass by and look back, the dot is there again at a distance. To my knowledge, this only occurs in multiplayer.



-The last one is just a graphical problem. Running at a high resolution is a hindrance in the game because when you see a contact at a distance and zoom in, it appears smaller (because you are rendering 1 pixel). However, if you are rendering at a low resolution, you can easily see contacts at a distance. The worst is that bombers, boats, and balloons seem to explode from a small do to a 3d object. Also, clouds seem to magically appear at a distance of ~5000m away. Rendering needs some work. And something especially needs to be done for ground object rendering. It is impossible for player bombers to see and line up on a target for a level bomb because they do not render ground objects until they are within 5000m. So for a bomber trying to hit a factory complex at 5000m, you are literally over the target by the time you can render it.

Because of the scale of the game, I would suggest allowing the mission builder to designate objects that will forcibly render at a distance.

where are tanks destroyed?? if you kills tanks, there are only shadows...... seems that the maximum of the developers is: if it fails, remove it

I keep get this and I am not running out of resources. 16 Gb ram and 3 Gb vram. Monitoring shows I have plenty of resources left over. Never happened until this patch. Yes, I know how to change the desktop composition, but this is an error specific to CoD application. Should not happen.

I have had this all along. I only get it in menus, maybe it is something to do with the interface coding.

A first for me...

Sudden FPS drops when zoomed in, the two shots here are first zoomed out and i was getting 48 FPS and pretty smooth, the second full zoom and FPS dropped to 3!

Note not looking at lots of aircraft, clouds or lots of land detail.

Had to stop playing as it was horrible.

This was on ATAG, lots of lag when over 50 people playing(not ATAGS fault)

Significant frame rate decrease over previous " version" when dust, smoke ,fire, vapor are experienced. When flying toward the sun I can barely see past the spinning prop, however with the sun to the my back no problem( must be a lighting issue). Low flying EA aircraft crash into water when manuvuering ( new for me). The entire sim now looks very muted and washed out in and out of the cockpit.

This is a new bug for me too, when zoomed in (appears most often over water) and attacking enemy bombers the propeller visuals almost slow down to where the screen is very choppy in this zoom area (the sides are clear) so its ONLY in the zoomed in gum area. Seems not to matter if I turn down the resolution down or up, or if I have visual effects set to med or high, its something I have never seen before, and yes, my anti epilepsy settings are set to off. It's strange. I'll try to take some screenshots or a video. Its the only glitch Im picking up with the game so far.

P.s. Dust upon landing and take off still are significant frame eaters, worse on high visual effects, still present on medium, and in both cases, the dust appears if your in the cockpit to come through the bottom of the plane.a bit strange

Exactly the same on my system and never seen this before either. AI bomber formations have always been safe for me to approach (except for the bullets) but now they hurt my framerate badly. A shame because this patch seems to have fixed many visual problems.

Actually this is the last big issue with performance! But it is a game breaker!
