Sub2K

I don't want to resurrect this old thread, but I want to pass on that the helpful folks here were right: I upgraded to an i7-8700K, and my DCS frame rate has easily more than doubled. That definitely confirms that I was greatly CPU-bound with my good 'ol 2600K... :(

I'm new on the forum and your guides are gold. Thanks a lot!!

@ David OC, My 3 x 1080p monitors are all connected with individual DisplayPort cables to the 1080 Ti. I no longer use Nvidia Surround as I found it to be a bit 'flaky' at times. I simply setup my monitors as '3 Screen' and 5.33 aspect ratio in DCS.

@TJ, If I'm gonna upgrade my three 1080 monitors to three 1440..... I'm gonna need a loan!... ;)

@ElementLT, I already had it selected, but I now also selected the other settings that I can see on your screenshot. I'll give them a try. :)

@TJ, Actually, since I'm using 3 x 1080p monitors, I'm at 5760.

@ TJ, Actually, that screencap was taken over Dubai. Also, I have my pagefile set to 16 GB. Could that be the difference?

@TJ, Unfortunately, the native resolution of 2 of my 3 monitors is 1080.

@derodo, Alright then. I guess we wait for Vulkan... :(

@ Headwarp @ Aluminum Donkey Finally! I've attached two screencaps taken in Free Flight over Dubai: - My current settings - My Task Manager resources See anything weird/unusual?? P.S. I've since turned off Smoke Density.

@Headwarp, Thanks for some good insight into your experience and for providing some recommendations. I use a TrackIR 5 and I would be thrilled if I could get a steady 45 FPS. Unfortunately, as I mentioned in my previous posts, I seem to be stuck in low 20s ad vitam aeternam. I also get up to 60 FPS when I'm basically looking at... nothing. I'll keep my trials and errors testing going, and hope that Vulkan may help us all someday. :)

@TJ, I just checked, and my RAM usage holds steady at 57% (about 13.7 GB/24 GB). As soon as I can upload a screenshot, I'll post my settings.

@erniedaoage, Good suggestion, but I have tried both Windowed and Fullscreen with no change in FPS.

I agree with everything you mentioned TJ, now I just need to figure out how to 'tune' my system to take advantage of the new card as much as possible. BTW, I just ran the Single Threaded CPU MARK and got 2391 (91th Percentile) - They sure don't make things like they used to... :) Thanks a lot for all the feedback/help!

@TJ, I just downloaded and ran Passmark, and I got the following (typed since I can't upload an image): PASSMARK: 5072 (92nd percentile) CPU MARK: 8855 (75th Percentile) 2D MARK: 777 (76th Percentile) 3D MARK: 12745 (98th Percentile) MEMORY MARK: 2504 (83rd Percentile) You'd think I could run DCS 2.5 properly...

@TJ, I currently have 24 GB of DDR3 (had 16 GB previously). I really haven't noticed a difference though.

@Tj1376, I'm sure you're right about the 2600K. Thanks for the heads-up on the new CPU release. I'll keep my eye on it!

@derodo, According to thebottlenecker.com, this CPU/GPU combo was only supposed to only have a slight bottleneck (although it only offers the stock 2600K at 3.4GHz, and mine is OC'd to 4.4), so I thought I was safe. My fear is I already spent over CAD$1200 for this 1080 Ti, and what if I go out and buy new CPU/MB/RAM for $$$ and DCS's FPS still don't go up very much. That's a lot of $ (which I don't have) for one game/sim. I'll try bringing down the trees, but I'm sure the rendering will be very disappointing. Thanks for the constructive input!

@BoneDust, At this point, I would settle for a 15 FPS gain... :(

@derodo, To be honest, I haven't checked whether my i7-2600K is bottlenecking DCS (it's been such a great CPU for everything else) . Doesn't DCS use all cores? You got me scared that a CPU/MB/RAM upgrade is required to see some better frame rates... :(

@ Aluminum Donkey, Tks! It's just unfortunate (so far) that the upgrade doesn't help. And... Check, Check and Check on the suggestions.

@toutenglisse, That was for 1.5 though. I was really hoping that it wouldn't be the case in 2.5. :(

Badlego: I only replaced my video card, those wouldn't change.

Hey Mustang, I tried to upload a screencap for you, but I'm asked for a URL address when I click on 'Insert Image'... Is it because I'm new and don't have enough posts yet?

I just upgraded from a GTX 1060 6GB card to a 1080 Ti FTW3 specifically to increase performance in DCS 2.5, and my frame rate still sits at around 22 FPS (even when I change settings) when I'm 'Ready on the Ramp' in the Persian Gulf map. The 1080 Ti is giving me fantastic frame rates in all of my other games, so I assume this is a DCS problem. Any help appreciated. :helpsmilie:
