doright Posted August 27, 2013 Author Posted August 27, 2013 And this thread is about CPUs, not GPUs. Flight simmers are full of conspiracy theories about hardware.:joystick: Actually I started it as a question about compilers. Mainly from my frustration about AMD framerate in DCS when other games I play run great. You think ED would notice their customers probing and autopysing every file in hope of finding the one line that says AMD_cycle_abduction_mode = 1; Seemingly no acknowledgment from ED that a problem exists despite years of customer posts. Without that acknowledgment I have no hope that the vaunted EDGE will bring any relief. Interesting tidbits from many knowledgable people, from but NO answer from those who actually know. The truth is out there (oh no conspiracy theory time).

I think you are onto something there...Anyway if you dump the dcs.exe process who knows maybe you find something like "INTEL64" in there...but that would be more correct by ED than "blend" anyway or?

doright Posted August 27, 2013 Author Posted August 27, 2013 It was a riddle nobody solved yet. :) OK, What have you got in your pocketsess?
SkateZilla Posted August 27, 2013 Posted August 27, 2013 it's easy to claim DCS Favors Intel.... But to say it was compiled using an IntelCompiler: When Intel Alone sports a 1.9-2.3 Single Core Score for their i Series Chips (1.9 being first Gen iSeries, 2.3 Being Haswell) vs 1.3-1.6 for AMD Single Core Score (1.3 Being the First FX Series Score, 1.5 being Pile Driver and 1.6 Being Phenom II). And DCS Being a Dual Thread (with 1 thread being sound, and 1 thread being everything else). Then that argument gets thrown out the window.

The truth is out there (oh no conspiracy theory time). Are you talking about GPUs or CPUs? Fwiw, I have an intel cpu and amd gpu and DCS runs fine. Other flight sims also run very well with my amd gpu. I've owned both nvidia and amd gpus, and so far as I can tell the biggest difference between them is price, i.e. you get more for your money with an amd gpu because of the cache attached to nvidia.

And DCS Being a Dual Thread (with 1 thread being sound, and 1 thread being everything else). Then that argument gets thrown out the window. In case you forgot here is my original question: "Does DCS use a compiler that has AMD optimizations enabled or just Intel (or worse yet the Intel compilers)? If not, could DCS try a beta with an AMD executable please!" Not really an argument, more a question (only slightly loaded). No definitely a question, I see a question mark at the end. I've plenty of experience with other games and simulators where it FPS doesn't make it nearly unplayable and I see significant overlap and only relatively small % differences in single core scores looking at a site using a different benchmark. Your "you hardware sucks" comments don't really help now, and certainly hasn't helped fix the problem in the past. Maybe, just maybe, you also would begin to question that it's something on ED's side if you weren't so busy defending them despite having no answer to the question. Shoot, maybe ED can just try a trial version of a different compiler and see if makes a difference.
SkateZilla Posted August 27, 2013 Posted August 27, 2013 (edited) I never said anything along the lines or even close to "Your hardware sucks". and if you think Im against AMD, then you need to take a look at my specs in my signature and my facebook profile. The Answer is Simple. DCS is 2 Threads, one for Sound, one with EVERYTHING Else. AMD CHIPS from PhenomII->FX BullDozer->FX Piledriver have dropped in Single Thread IPC Performance, while Intel has Pulled away. DirectX9.0C has a Significant CPU Overhead when rendering more than 500 object Calls. which means more work actually falls back to the CPU Driving the DirectX Calls. Intel in Dual/Single Threaded Applications is nearly 30% faster than AMD, using Instruction Benchmarks. (Both Command System and DirectX Calls). AMD's Architecture has moved on to favor Parallelism of Threads. Intel is still pushing Single Thread Performance. AMD is about 5 years too early with the Parallelism. as for AMD Compilers... Like I said, this isnt 1998, where AMD Was winning the Battle with K-6II's. And Intel fought back by having Software Companies compile their benchmarks/applications to favor Intel. Most of AMD's Specific Instruction Enhancements (most notably 3D Now!) dont exist in the newer AMD CPU's, So there's really no point in re-compiling with an "AMD" Compiler. AMD has a License to use Intel's SSE Technology/Instruction Sets The only way to get something to run well on an AMD Chip is to make it several paralleled threads. The Data is there, the answer is simple. AMD+AMD = Lower FPS than Intel+AMD, or Intel+nVidia. The Common Component in the Better performing systems is the Intel Chip, not because DCS was compiled for Intel's Chips, but because Intel's Architecture runs Single and Dual Threaded Applications significantly faster than AMD. And when Things start to hit the CPU Hard, Intel Shines more.
