Hi Guys I have wanted to overclock my system for sometime to see if I can gain better performance using my Oculus Rift but obviously dont want to cook my GPU or CPU. My Bios was last updated at Christmas I currently just use a program called Razor cortex which seems to help free up available memory and also to see my system CPU-Z with oculus tray tool running as well. I have seen a program called MSI Afterburner which lets you tune your system, what our your views on this software ? My set up is as follows Gigabyte X470 motherboard, 32gb corsair 3200 ddr4, AMD Ryzen 7 3700X, Ml240 liquid coolmaster, Nvidia GTX1080ti 11gb, 1Tb ssd Seagate drive with about 400gb space for Prepar3dv4.5 ,Oculus rift CV1, X52 joystick and throttle. Addons I have are ORBX Scenery ,ASCA, pmdg737, Aerosoft A318,a321.

Performance wise at the minute I get about 20fps thats using ORBX Scenery, with Just Flights Hawk T1 with Oculus rift CV1 and OTT running. My settings in Prepar3d are. Display screen FXAA on. AA is 4x MSAA Texture filtering Antistropic 16x texture resolution 1024x1024 Full screen settings 1024x768 vsync is off.
World settings are LOD radius High, Tesellation factor High, Mesh resolution 19m, Texture res 15cm, Scenery complexity is Dense, Autogen scenery is Medium, No Auto vegetation or buildings, Water detail low, no reflections, Special effects both medium.
Lighting is just dynamic reflections low with landing lights illuminate ground

Any advice or ideas would be much appreciated

MSI afterburner is fine, and so is the EVGA tool, and the ASUS 'GPU Tweak" tool. I have used them all, here is my advice :

- Try to get your CPU overclocked as a first step.  At least get it over 4GHz, shoot for 4.5 to 4.8 would be even better.  I didnt see your CPU clock rate listed in your post.  Get that done as step 1 and ensure that the system runs stable, no crashes, no Windows blue screen, etc. 

- THEN use one of the GPU tools to OC your graphics card.  I didnt see who is the mfr of your 1080Ti but I like to stick with the mfrs package - in other words, right now I have an ASUS card, so I use the ASUS OC utility, not MSI.  On another machine, we have an MSI MB and video card, so we use MSI utilities on that one.  Just a personal preference.  I have the card overclocked to about 1700MHz on avg.  

Even with all that, you'll only see incremental improvements in performance.  Turn down any traffic, try MSAA on a lower setting, and reduce Autogen a bit.  Those will also help your VR experience.  

best, 

I can’t comment on the performance of the hawk but I can say it sounds like something isn’t working right if your only getting 20fps. I was getting way more than 20fps on an odyssey+ with a Ryzen 5 2600 and a 2060, which I’ve upgraded this past week to a 3600 and a 2070 super.

random thought...have you changed your VR settings in P3D to single pass? If not try that first...
