That also is now gone and control is inmedeate.
Normaly I would get 11FPS while doing that now its going down only to 25 FPS.
While tinkering I found that my overall FPS doesnt go below 42 very low on the deck or with explosions and so on.

Thank you NKS61 for taking the time to test and thanks for posting a measurable and reproducable result!

This is the moment when you have half the fps you normally do. So, your 40fps turn to 20fps (it takes much longer to load textures to the VRAM of your GPU than having these textures already loaded on the extremely fast GDDR5 VRAM).
In addition to the above (halved fps), when you have the required textures on your "slow" hard disk then it takes even longer to load them (your seconds delay in the past) onto the VRAM of your GPU. HERE THE RAMDISK HELPED
So, putting everything back together, the moment you reach the 99% allocation of your VRAM, your fps will be badly hit. If you know this, you can control it by removing certain graphics options.
Extreme situations (like the terrible dust clouds) will always happen. By the way, you mentionned a "harmless" example; My problem is when a big bomber explodes in front of me and parts fly in the air...
The highest amount of VRAM utilisation posted by some users in the forum was 2,4Gb VRAM so I dare say that pre-bigPatch, only the 3Gb GTX580 and 2,5Gb GTX570 versions do not run risks of overfilling their available VRAM.
