jewnham, what practical benefits did you see from lowering Pre-render to 1? Less blurries or what?

I thought I explained that in my post. In areas where your CPU may struggle, the pre-render 1 will "HELP" to smoothe it out buy sending data to the GPU on a frame to frame comparison instead of asking the CPU to render 3 frames before sending them to the GPU. Let me put it this way.... imagine you are on a sinking boat and you are taking on water. On the boat (FSX) there is another container (pre-render) that will allow you to dump 3 buckets of water into it and then you dump it. Then your friend on board (me) says... why not just dump the water right away over board in place of collecting 3 before removing it from the boat? That way you are removing water at a faster rate and at a more consistant rate and will actually make a difference faster versus waiting to dump 3 buckets. If the water was entering at a rate that matched your 1 bucket at a time you would stay afloat. If you waited to first collect 3 buckets then dump it eventually it would catch up with you and you would sink (stutter).

You are not answering my question. I understand all that technical explanation. I will ask again: What PRACTICAL benefits did you notice with that change? In other words, what difference do you see inside the simulator?

I've seen no practical application of this in the performance of the simulator. But, in the combination with the BP=0, it's a must for me, otherwise I'm gonna very easily get snow-showers on the screen (artifacts). Using prerender 1 never brought me artifacts.

I use FFTF 0.33 here. I just tried FFTF=0 and got lots of blurries. Can't use it.FWIW.

Did you check the other thread about this, especially concerning other settings in fsx.cfg? They are in the 3rd post down.Please if you still wish to try it, go there, set all you can set and then test. Reply over there your findings. Much obliged :(

It helps to take out lag in areas that your CPU is being pounded.

Is that with a locked frame rate in FSX?If I set FFTF=0 with fps=unlimited and then limit it outside the simulator,I also get lots of blurries.

No, it was with external limiter locking to 30 FPS or with unlimited without external limiter.Once i tried without external limiter and locking inside FSX instead, i get no blurries.But this is being discussed on the other thread, guess we have 2 threads on the same subject.

Let's go into a new topic: why is it there, and does everyone have it?Simple thing: VSync off, no FPS limiter, no internal limit: FPS shows for instance 50.You set the limit just to 99 - what happens? FPS drop to 40.Happens with all aircraft and everywhere, no matter what addon you are using. Not tested with vanilla FSX.The drop is usually percentage, I can't say exactly how much, but to me it seems about 25-30%.Can we try and find out why?EDIT: Corrected some things as I did false tests...

I think it was NickN who said UNLIMITED gets some optimizations (I guess you knew that already and are looking for elaboration) that limited frames does not afford. This is why the external limiter, FPS_limiter.exe is such a useful tool. You get the best of both worlds, at least that has been my experience, and many others. Noel

My .cfg file as created by the tool: 1. Does not have a line for FFTF...so presume that the tool has "decided" that FFTF will not suit my system?2. The line "Shader_Cache_Version XXXXXXX" is also not in the .cfg file however I do have a similar line "Shader_Cache_Primed XXXXXXX" ?????????My system is XP, Asus P5Q Mobo 4GB DDR3 RAM Intel Q9250 Core 2 Quad and an Nvidia 9800GT Card with 1GB RAM.Perhaps my system is too old for any benfit????
