With some of the workload being passed off to the GPU in V2, will it be necessary to do extreme overclocks to get good frame rates. My rig, a 4820K on a Sabertooth board and a GTX 680 4GB. With FSX, decent frames for me, with my settings and add-ons, comes at 4.6 GHZ. Should I be able to back that overclock down? I'd like this chip to last for awhile.

My system: i7-4770K Haswell overclocked to 4.2 MHz; ASUS Z87-Deluxe motherboard; EVGA GeForce GTX 780 3GB SC w/ ACX Cooler.

 

With just default P3D, I'm getting an average of 30 FPS in Boston (day and night), with nearly everything set to maximum (shadows are set to Normal Quality). Away from the city, I'm averaging about 40 FPS (with autogen trees set to max), and 50 FPS when I reduce the setting a bit.  But I'm just flying small planes.

As long as your temps are good and your Vcore isn't too high you can run a chip coverclocked for a long time look at the new AMD 5ghz thats just a factory overclocked 8350

Hmm

 

I've got an I980X with a 4-gig gtx680 and a 4770k with a 3-gig 780. Not sure which rig I should use for the install.

 

2hrs before I can head for home :(

Is that with all shadows enabled? So also buildings, vegetation, terrain? If so, I might have to get that GTX780... My GTX580 drops dead when I enable those shadows.

I'm still tweaking my settings, plus I just installed FTX: Global, so I won't be able to test this with default scenery.  I didn't have all the shadows on, but I know that I had buildings shadows on.  

 

I did just get a OOM in a later flight (after installing FTX) . . . when I was seeing how far I could push the settings near my home airport (where it's pretty mountainous), with maximum autogen (including maximum trees) and everything else set on max, I was still getting FPS between 40 and 50, but I think what happened is that I ran out of VRAM (my 780 has 3 GB).  Lowering my Target FPS to 40,  seems to have solve the problem completely.

 

This is going to take some getting use to, as you can apparently still be getting great FPS, and then suddenly run out of memory with no warning.

my old school 3.6ghz rig used to run at 99% load with fsx, with p3d it's at like 20%. really seems like the cpu doesn't matter as much for sure.

like z06030 said though, if your clock is stable and temps are decent it's probably not going to substantially affect the chip's life.

Jw are you seeing any stutters with you 780?

The frame rates are much better now but the cpu is still the bottle neck with higher end gpus. You really need to look at gpu and cpu usage to judge if the cpu is or is not the bottle neck. If the gpu usage is less than 90% you can bet its the cpu that is holding it back.
