    Question Multi Core CPU optimization & SLI/Crossfire support?

    Well here we are at the end of this year, & Rome II is still not optimized. My CPU only runs at 40% because multi core CPU optimization is still a joke right now. 2 processors run at 70%, 2 processors run at 20%, & my other 4 processors run at 5%. Is this ever going to be fixed? Also when are we going to get SLI support? I have almost completely quit playing because I want to play this game the way it is meant to be played. Is there going to be anymore optimization for Rome II, or is AI & balancing all that CA is working on from now on? I want the same level of optimization for Rome II that Shogun 2 has. Is that expecting too much? Please CA? Please?

    I just wonder how much longer they can keep trying to fix the game before they say f it and move on to the next one. A year seems like along time to keep using resources to patch a game.

    I really doubt they can fix it. It's the engine but still I have seen vids (didnt play shogun 2) and it runs much better

    They will continue patching at least until all DLC has been released. My problem is that optimization should have been priority one. Everything else should be fixed after optimization. Why are they dragging their feet on this?

    They can fix it. Shogun 2 had the same problems for a few months after launch, but it wasn't this bad. I really hope CA makes optimization their highest priority for patch 9.

    What exactly do you think the CPU usage of a properly optimized game looks like? You seem to think that because the CPUs aren't under heavy load the game isn't optimized.

    The game has 36 threads whenever I launch it. If 36 threads aren't loading up the CPUs then the threads are I/O bound or simply not doing anything at that moment. And if they're I/O bound then you can't optimize that really.

    This game is heavily CPU bound. You need a top notch CPU to be able to run all these models in large scale and then a $600 video card to run shadows and particles. I think this game will run better on an ATI card than NVIDIA because of the fact that ATI cards are better with computation. Just take a look at how bitcoins are mined, same concept when you need to calculate all those models running around.

    To tell you the truth, I don't think this game utilizes anything over 4 cores. The game might only be optimized for 2 cores even. I have the newer i5 4750k processor and it has 4 cores and 4 threads and all cores run at 100%. I know the newer haswell processors are suppose to be able distribute the load evenly across all cores. However, I can't be sure because I thought I read something about only certain haswell models were getting the new special instructions. So I don't know if it's the hardware or the game's programming that is causing all 4 cores to run at 100%.

    This game's engine is Total War ****. It's using the same engine as Empire and Shogun 2, which were also ****. They actually made it worse because of all the stupid one-on-one animations they've added. They paid way too much money for animation actors. Especially for something that's over in 3 minutes. In Rome 1, it was more simplified, but it made sense for a strategy game when dealing with mass combat. A charge was determined by distance and time, which is how it should be. All the stupid micro managing adds more calculations that drops performance.

    They made a game that simply wasn't meant to be run on the present hardware. They're going to be in for the long haul. Shogun 3 was supported for 3 years. I don't think this game is even close to being finished. They may even add an enhanced graphics version after they figure out what the hell they've actually developed.

    You are not understanding me I guess. I am not saying the game should max out all 8 of my threads. I am saying that it should spread the load evenly. I should be able to max out everything on this game with my rig, but with no SLI support yet, & the CPU usage not properly using my Haswell i7 CPU threads I am stuck at a little below maxed out to get a stable 60fps in game. Shogun 2 runs twice as good for me. I know this a newer & more demanding game, but considering I get 80fps in game with Shogun 2 maxed out I think I should at least get 60fps in game with Rome II maxed out. Are you saying that I am wrong about this?

    My settings are all Extreme except Shadows=Ultra & Unit Size=Medium. All special effects on & maxed out except Alpha Vegetation & SSAO turned off. 55 to 62fps in game 47fps average on benchmark test @ 1920x1080.

    If or when we get SLI support I should be able to max everything, but the CPU usage still bothers me greatly. I thought this was a modern game designed for modern hardware. CA specifically suggested Haswell i7, & that is what I have. Maybe I am being over critical, but I just want the same optimization for Rome II that Shogun 2 has. I still don't think that is asking too much.

    I actually had to unpark my threads to even get them all to work. Before only 2 cores were being used & I was getting terrible performance. Just to be clear that is why I say CA needs to optimize CPU usage. Why should I have to unpark my CPU to get the game to recognize more processors?

    Yes. Thread-to-core assignment is handled by the OS and hardware - not the game.

    So you needed to tell your OS to not put some cores into power saving mode to get better performance. That is CA's fault how?

    Thanks for the tip though I'll try this on my rig.

    You are welcome for the tip, but that still doesn't explain why most games will use all of my processors without having to manually unpark my CPU & Rome II will only use 2 out of 8 processors unless the CPU is manually unparked. That is an optimization problem on CA's end. Not the OS or hardware. Every game is optimized to use a specific number of processors. Very old games will only use one. Games a little bit newer will use 2. Most games released after 2009 will use 4 or more. So explain why Rome II only wants to use 2? I can tell you why... CA has done a poor job of CPU optimization for this game, & they need to fix it asap. I am using Windows 7 Pro 64-bit, & this one game is the only game I have with this issue. So I know it is on CA's end. Even Shogun 2 uses my CPU properly.

    so Shogun2 uses all cores correct? does it use CPU far beyond GPU too? can't really check this myself because I start Rome2 or Shogun2,my CPU and GPU is both 100% usage,so my entire PC is bottlenecking even Shogun2
