Use a RAM drive to reduce stuttering

Mind also that a lot of limitations arise from loading/ unloading a lot of graphics details from the hard disk on to the RAM and, the Video RAM (as the plane flies over large distances).


So there is something to be won.

Now, it all depends by the speed of your hard disk (ms, cache, NCQ, transfer rate, fragmantation) and yes, you may get serious stutters.

Since a lot of us bit the bullet and spent a lot of money on new HW and new hard disks, I believe most of us have very optimised hardware (thus no stutters).
But for some people it may be of help.

I believe a RAMDRIVE is better than a SSD because (hopefully) the transfer rate should be much faster (the SSD has to go through the SATA channel after all).

Anyway, I increased my RAM by 6Gb to 12GB because I was curious yesterday.
Created a 6Gb RAMDISK and loaded the whole CoD on it.
I can not say I noticed any substantial difference (on the other side, I do not think I ever had stutters either).
I run SLI GTX570 and my problem is that over land the GPU utilisation drops at 50%-60% against 99% over sea and wanted to see if the RAMDISK would solve some of this.
It did not really although I noticed at times that my GPUs went to 70%-80% above land.
On the other side, I was flying yesterday on the REPKA server for about 1,5hrs at nice 50fps and no stutter at all and very smooth game (it looks to me more like a placebo effect).


~S~

The problem is optimization and VRAM loading, maybe, not RAM usage or disk access at all. Because of that, all the RAMDISK route don't do substantial improvement, as in ArmAII. ArmAII problems arise in early versions because all LOD loading and texture streaming don't priorize right.

You don't understand my words, because my english sucks... That's no need to IL-2 COD use more RAM than it uses now. That's not the problem. We can have smooth gameplay sometimes, and in other flight in the same conditions, stutters. And we can't see consistent improvement using RAMDISK.

So, conclusions are easy.
