Upgrade 4770k/980 Ti to 8700k/1080 Ti: Results in 2.5 VR

[aaron886]

This is totally anecdotal, no charts and graphs. However, I know I browsed this forum hoping to find this kind of information and came up short, so hopefully this helps someone.

 

Settings:

PD 1.3

I spend the majority of my DCS time doing aerobatics, often with a lot of diverse air units around and at low altitude. That said, there's not much in the way of ground units or AI combat being calculated, so YMMV.

 

Old system:

4770k OCd to 4.4 GHz

ASUS Z87A

G.SKILL Ripjaws 16 GB DDR3 at 2400 MHz (CL 14)

EVGA 980 Ti SC

 

Low altitude over Senaki: 45 (ASW) with frequent dips below.

Medium altitude: 45 with occasional dips below

At high altitude: 45 constantly

 

New system:

8700k stock

ASUS Z370-A PRIME

Corsair Vengeance LPX 16 GB DDR4 at 3000 MHz (CL 15)

EVGA 1080 Ti FTW3 Hybrid (Liquid/Air)

 

Low altitude over Senaki: 45 constantly, never dips below 45

Medium altitude: 90, occasionally locks to 45 (ASW)

High altitude: 90 constantly

 

During the upgrade, as parts arrived, I had the 8700k and 980 Ti paired together when 2.5 first dropped. With similar settings, the results were more akin to the old system but with a reduction of dips below 45 FPS. Conclusion? 1080 Ti is an absolute beast.

What manufacturer card?

As not all setups get even 45 fps.

unpacking my rift tonight, curious to see this.

 

With TiT, MP, I never dropped below 100fps !!!!!!! With Trees, Grass etc all maxed out ( def off ).

 

Performance wise 2.5 is a Turbocharged Kompressor driven V8 with Edelbrock heads, it roars and flies

Overclocking your 8700k will improve things a fair bit probably. Out of the box it only does 4.3 GHz unless you have process lasso put all 50 or so windows threads onto a single CPU thread. Getting 4.7 GHz for all cores all the time at below stock voltage was trivial on my Mobo. That will bump performance up pretty well. 5.0 GHz is also doable but I find it doesn't make much of a difference in DCS. No delidding is required. I use a simple push/pull 120×49mm AIO, so nothing too crazy is needed for cooling.

 

My system runs the Rift mostly locked at 90 fps on the deck with high-ish settings and 1.3 PD.

Good to hear an overclock might improve things further, because with my AIO I never saw above ~40C temps in DCS. Tons of headroom. That really surprised me, my 4770k ran significantly hotter even without the OC.

Ohh man I hate reading stuff like this, as it tempts me. I am planning a new build this year but was hoping to wait more towards the end of the year.

Watch your GPU usage %, if it drops below 99% your CPU is falling behind.

 

I had 88% last night with 5G on the CPU but the GPU was cranked up too to 2025/12000 and ran away.

 

So today, I engaged the 5.2G again to keep pace.

If more CPU speed matters is determined by your GPU !
