You can do all that in the Hog as well. Its just that in the 25 you have no other option. I like to start people off in the 25 as they dont have any crutches (hud,TGP,etc) so they are forced to learn the basics of airmanship. When it comes to combat the fundamentals are the same between both aircraft with the exception that the Hog taunts you with all the automation so alot of people don focus on the basics e.g unguided rockets,bombs,HADB, MAT techniques etc.

It really depends on the application for example AD will not run at all w/o a swap file even if you have 128GB in the system. Some apps perform better w/o a swap as well. But generally speaking you should have a swap at least as big as whatever you have your kernel dump configured for in case of a crash on my 8GB system the swap is set for max of 2GB on my 16GB system its set to a max of 1GB. right now on my 16GB system even with a total commit of 4.8GB of 18 only 4.5 GB of physical is being used. Its cached file descriptors and parts of inactive applications that arent changing

RAM use is not the only metric to watch..you should also look at the program's and systems total commit size as that is the total amount of memory the application/system has requested. depending on what programs you have running total commit may or may not be larger than physical ram. Also note that due to the system caching file handles and such your total commit can grow over time. On my system with 8GB of physical ram the my total commit is about 8.3GB including DCS,trackIR,TS3,Helios,etc. It starts out around 6.9 but does grow after about 90 min of flying. It peaked out at 8.3 so I set a 1-2GB swap file to give me overhead. Im on an SSD so telling windows to start with 1GB and max 2GB is appropriate.

You should never disable swap. Some programs won't even run w/o swap. That being said its ok to set it to a very small value.

These articles are some of the best about how windows manages resources. That are a bit old but still relevant.

I also wouldnt call it a problem. I would love to Average in the 60s but thats unlikely as i run multiple monitors (no full screen as I havent setup SoftTH yet).

As soon as all my parts show up ill assemble and let you all know how it goes.

On my machine DCS.exe has a commit size of over 5GB so in your case with only 4GB of total system ram you will be swapping out a bit. I also want to point out that in your "test" mission even without units your flying over a city that has objects. To get a baseline you should compare the two cards on a mission in the middle of nowhere and record FPS/%GPU Util/%CPU Util/%VRAM/%System RAM. This will be your best case scenario and you know it will never get better than this as there are no objects affecting anything. From there we can see if there are any bottlenecks in the most basic of tests. If there are they will be even worse and possibly be masked by other issues. That is if you want to conclusively see: 1. What is the bottleneck on your system 2. measure the difference between hardware 3. measure difference between settings changes 4. measure differences between different objects in the world You should really read through that link i posted again and run all the tests mentioned there and capture the data i mentioned above. With slow FPS is a symptom but not indicative of the cause also what EtherialN said is dead on. I never pay attention to synthetic tests and game benchmarks unless they are specific to simulations as they are very different beasts

What were the % utilization of GPU, CPU,Vram and RAM during these tests. Without any diagnostic data there is now way to know how/if this can be tuned away

My bad in my post for sending you down the wrong path...i ment "...GPU speed as well as memory" and by memory specifically GPU VRAM

also you may want to consider a better (IMHO) alternative than 5040x1080 + helios that will help with performance

If you want a good systematic approach to performance in DCS read this thread. Your benchmarking with too many unknowns but if I had to guess on your problem it would be the CPU

why 670 and not 770? get about 10% increase in perf or so

your profiles are in Saved Games so if you uninstall and reinstall they wont be touched but i still keep backups for other reasons

its definitely "Bleeding Edge" at this point. So was TrackIr back in the day

You can tell when a profile is loaded when the background on the icon in the task tray is green.

CPU is most likely fine. Run process explorer from here and it will show you the load on the CPU and GPU and a bunch of other data. I suspect that you are limited by GPU speed as well as video memory. I run 1920x1840 and use most of the 2GB vram on my 6970. What you want to look for is when the stuttering starts/happening check the GPU % utilization as well as GPU memory utilization and CPU utilization. Also check out Radeon Pro for tuning your card. Its much better than CCC and you can even enable an overlay that will show %GPU and a bunch of other metrics while flying so you can check on your card "in game"

Fair'nuff. I dont like Saitek's profiler software as i have personally had problems with it. I use TARGET for FC3 but not the simple gui mode, just the advanced mode as you can do some really cool things with it like have the FC3 aircraft's autopilots behave like the A-10C's does based on switch position and such

FYI I think its an issue with my specific configuration but sometimes even if the profile is loaded it quits working in game on random intervals. Just thought i would put that out there as it appears im the only one experiencing that issue

attached a sample profile for combat pro pedals FC3-CombatPedals.zip

Why not just do it in the Saitek profile software? Or are you having problems with it?

For a list of keyboard commands, launch DCS go to Options and click on the "Controls" tab Select the Aircraft you are interested in and and click "Make HTML" on the lower right of the screen. This will create HTML pages for each device you have connected in Saved Games\DCS\InputLayoutsTxt\<Aircraft> For keys click on the Keyboard.html This is better IMHO than having them listed in the manual as this will be specific to your computer/device/configuration

snap views are aircraft specific so you must set them up in each aircraft. Thats why PeterP includes a link to a mission with all the aircraft in it so you can just load it and setup each aircraft

with your current rig how much cpu/gpu are you currently using while flying?

How many monitors(resolution) you going to run. Thats going to be the biggest determining factor in performance. If anything more than one monitor at 1920x1080/1200 2GBvram is going to be tight
