A year has passed since I’ve upgraded my rig and benchmarked the process. In the year since I went over couple of overclock itterations most as a gutshot. In addition DCS has come a long way, 2.5 which is more VR focused had released and the community has stepped up with a VR performance mod.
So let the testing begin!
The system being tested.
|RAM||32GB of DDR4 rated at 3200Mhz (4*8GB)|
|Motherboard||Asus Maximus X Hero|
|Graphic Cards||Gigabyte GTX1080 G1 |
Gigabyte GTX750 1GB
System has Dual Graphics card for multiple screens cockpit.
1080 is used for graphics in game.
second card only does 2d stuff and video encoding.
|Storage|| OS is installed on Samsung 850 EVO 500GB (SATA 6G) |
Games are installed on Samsung 840 EVO 250GB (SATA 6G)
|Displays|| Full screen: 4K monitor (on 1080 Via DisplayPort). |
VR: HTC Vive, (HDMI to GTX1080.
(System has 5 screens connected on all tests.
Only difference is the virtual location of those screens.)
The test will be simple.
DCS settings, GPU overclock and running software are all maintained fixed. nothing changes but the CPU settings in BIOS.
Benchmark itself includes running 3 runs of synthetic tests, Cinebench R15 and CPU-Z both single and all core tests.
then two runs of a DCS SU-25T track in Caucasus theater. one run with stock DCS and a second run with Kegetys’ shader mod.
FPS data was gathered over the 10 minute replay with FRAPS, recording avarage FPS for every second.
SteamVR was used (HTC VIVE) set to Async Reprojection, thus allowing framerate to be floating between 45 and 90 rather then sticking to one or the other.
the OC settings tested are as followed:
- Stock 8700K, default BIOS settings
- XMP and MultiCore Enhancement (MCE) enabled in BIOS
- XMP, MCE and Sync All cores (i.e all cores 4.7Ghz)
- 5.2Ghz overclock based on Der8aur’s Hero X OC guide.
- 5.2Ghz overclock with HyperThreading Turned off.
