Default Overclock 8700k for DCS or not ?

Hey guys,

I'm a bit torn. I'm pretty happy with the performance of DCS on my current rig (in sig below) on which I am running everything at stock speeds however I always have that thought in the back of my mind of how much better could DCS perform if I pushed my 8700k with an overclock beyond what it does out of the box. Currently I'm running 3 IPS monitors in portrait surround at 3240x1920 and I'm at 60fps most of the time with the exceptional dip to about 55 and at worst cases, around 45 fps give or take in extremely populated areas. Only problem with that is since my setup has my monitors smack in front of my face, a dip below 60fps is somewhat noticeable on three 60Hz monitors all acting as one in Nvidia Surround mode. I've also considered ditching the 3 monitor setup and going for a single large monitor as I'm sure that my 1080 Ti is likely losing some performance given that it has to run Nvidia Surround (correct me if I'm wrong here).

1. From your experience, do you guys see any value in putting in the time and effort to overclock my CPU in terms of how much performance gain I may attain in DCS?

2. Would I technically gain performance in moving away from 3 monitor nVidia Surround to a single monitor at the same 3240x1920 resolution?

Does your GPU hit 98-100% usage ? If yes, no need to. If no, OCing the CPU should saturate the GPU better.

Use MSI Afterburner's OSD to find out

To #2: I guess not

My PC specs are very similar to yours, however I play DCS exclusively with VR rather than using multiple monitors (although both of these set-ups are very demanding on the GPU).

I have OC'd my 8700k to 4.9 GHz and personally I have noticed a slight but not significant improvement (vs. stock) for DCS. My Kraken x62 seldom goes above 50deg (whereas my 1080ti always runs hotter than my CPU).

But in your (and my) situation, I think you have to look at it like this:

If you have an 8700k, Z370 MB and Kraken x62, it would just be silly not to OC. If you are just going to run stock speeds, it would have been better to buy a non k chip (with bundled stock cooler eliminating the x62) and more basic MB.

Also, not a lot of time and effort is required to OC, if you don't go too crazy with it. I just incrementally bumped mine up every few weeks and then didn't feel the need to go beyond 4.9GHz due to diminishing returns and increasing likelihood of stressing my hardware.

It would appear that when I am running smooth at 60fps GPU usage is between 40-50%. But when My fps starts to drop, I notice GPU usage go as high as 80%

Is there an easy fool proof way to OC an 8700k? Heck, if I can gain 5FPS from am OC it would be worth my time given that my FPS doesn't drop below 52 FPS. The closer I am to 60 the better.

If you got a good CPU water cooler, then 5.0HZ is the must go for 8700K, in-game temperature should be kept below 70C, otherwise lower the frequency.

I agreed with the suggestions...Intel R Extreme ...is easy to use for safe OC. I have the same CPU and run it at 4.8mhz with a Kraken X52...temps are around 65 under max loads. Try Process Lasso as well, I found using it has helped DCS.

I delid'ed my heat shield. Takes 45min using RocketCool's tool. Very easy to do.

I use Thermaltake's AIO water cooler and have the 8700K running at 5.1GHz. For VR, it did make a difference.

It's such an easy thing to do, why not do it?

Its been years since I've overclocked and I'm scared

You can go @5GHz with no delid perfectly safe.

Is there a one popular go to guide that typically everyone uses to get started? I found this:

https://www.youtube.com/watch?v=pbRauc8gpQM

EDIT: I'm starting to feel a little more comfortable after watching that video. It seems simple enough. I think maybe if I start small and simple with a 4.8GHz OC at 1.30vcore and run that for a few weeks could be a good way to start.
