I have done several performance tests of my newest hardware and compared them with each other. I have used DCS World 2.8.3.38090 Open Beta with Single Thread ST and Multiple Threads MT with an Instant Mission: AH-64D, map "Marianas" - Battle for Saipan: Dawn Invasion" After starting the mission, I have pressed OK, then [Right-STRG + Break/Pause] for two times (for displaying the frame rate) and then I have pressed the space bar. Directly after that I have checked the frame rate. I know that my graphic settings are very hard.....: null All CPUs as well as GPUs are slightly overclocked, except the CPU Intel I5-13500. Here are the results, including the fps / framerates in DCS World with ST and MT: Here as a table: 4K performance comparison between four of my computers Type Description CPU GPU RAM DCS World Battle for Saipan – Dawn Invasion Time Spy Time Spy Extreme Port Royal ST MT Total Graphics Score CPU Score PC Self build Intel i7-12700KF (12 Cores, 25MB Cache) RTX 4090 24GB GDDR6X 64 DDR5-6000 84 98 („GPU-Bound“) 31977 37570 17394 16227 27128 PC Self build Intel i5-13500 (14 Cores, 24 MB Cache) RTX 3080 LHR 10GB GDDR6 32 DDR5-4800 48 58 („GPU-Bound“) 17325 17624 15810 8406 11529 PC Self build Intel i7-2600k @ 4.5 Ghz (4 Cores, 8MB Cache) RTX 2080 Ti 11GB GDDR6 16 DDR3-1600 21 38 (fast changes between „CPU-“ and „GPU-bound“) 9996 14096 3775 4506 8941 Notebook Alienware 17 R5 Intel i7-8750H (6 Cores, 8MB Cache, up to 3.9GHz with Turbo Boost) GTX 1070 OC 8GB GDDR5 32 DDR4-2666 6 7 („GPU-Bound“) 4404 4459 4118 1815 1030

Just starting a thread to post my results. Old Build: 5900x Water Cooled (liquid arctic cooler) Asus Hero MB w/ 64GB DDR4 3090 (not liquid cooled) 2 x 2TB Gen 3 NVME EVGA 1200 watt PSU New Build: AMD 7900x3D Water Cooled (Arctic liquid 360mm rad) Asus ROG Crosshair X670E Hero 64GB DC DDR5 6400 Ram MSI Suprim RTX 4090 Liquid X (Liquid Cooled) 4TB Gen 4 NVME (Kingston Fury) 2x2TB Gen 3 NVME Corsair HX1500i PSU NZXT H7 Flow I'll do some tests on the old system and post a screenshot of my settings so I can attempt a similar setup in the new system. All results are in VR on the HP G2 Reverb (Gen 1) Just waiting on the arctic liquid cooler before I can start my build, will run older system tests in the meantime. Not attempting a perfect scientific method comparison but will be as thorough as I have the patience to be to offer the community some semblance of comparison. For context, my 3090 build is severely CPU bound which is why I didn't attempt to get a 4090 for it. Most of the time the 3090 is not over 89% usage and many times is in the 60% usage area while the CPU is full tilt (20% OC'd) Not sure if the 7900x3D was the perfect buy over the 7950 but we'll see. Initial results show the two of them almost head to head, less than 1% difference (7950 edging it by a bit) but no DCS tests I've seen. The reason for the 7900x3D over the 7950x3D is the higher base clock speeds which should result in better single core performance and because its a 6+6 chiplet design over an 8+8 design there should be some extra headroom (in regards to heat) in the 6 chip design to squeeze more Over Clocking out of it as the 8 chip design will generate more heat and DCS won't use them anyway. Is my thinking correct on this, who knows, we'll find out soon enough. In the 5900x vs 5950x (I've run both) the 5900x was faster in my builds. Same was true in the 3900x generation. Either way, the difference would probably be insignificant. The real gains for me will be the extra CPU headroom over the 5900x for more draw calls to the 4090 which I'm hoping I can take much more advantage of than the 5900x did with the 3090. Excited to build this, but not sure when I'll be able to get around to it. Too many projects on the go and this build requires me to build 4 pcs essentially as I have a rotation of parts as I build new machines. (my old machine some parts to my son, and my sons old machine 3900x back to me for the office and my office machine back to one of my daughters etc.. etc..) I love upgrade time, but it will be busy on the workbench for a bit. Some parts sleeping under my desk until the cooler arrives.null

NOTE: I do not believe this is a DCS defect, however this behaviour commonly occurs when in DCS Problem At least twice a week (at times much more - i play DCS every evening) and within the first 15minutes of a SPlayer VR DCS session the following has been occurring over the last year - Black Screen, Fans 100 percent, hard-reset or power-cycle is the only option to restart (12VHPWR sense pin LED indicates normal signal) History I first encountered this issues last year with a new gaming rig however windows event viewer was reporting WHEA errors - in response i RMA'd the 4090 which turned out to have bad capacitors. About 3 months after installing the new 4090, i again started to encounter the same behaviour with similar frequency and symptoms. Just prior to black screen event, the Windows Event viewer reported the nebulous and useless Event ID 56 ACPI 2. I was able to eliminate this event from being reported by Windows by setting NVCPL to prefer max performance and restart (no fast start) PC prior to any DCS session. Over the last 10months i have tried many settings to resolve or at least minimize (see below). Currently the Windows Event Viewer reports (albeit with a timestamp nowhere near the black screen event) \Device\Video3 UCodeReset TDR occurred on GPID: 100. What i have tried to solve or at least mitigate Variations of this behaviour is littered en mass in forums across the internet (NVidia, Reddit, Overclock.net, etc.); as such and as expected with anything on the internet, the unstructured responses, recommendations, etc wildly vary from moronic, insulting, helpful. There is of course no systemic solution as influencing hardware, software, OS & BIOS configuration varies materially enough that a resolution for one particular person's ecosystem does not work for others. Removed all useless bloatware e.g. gamebars, overlays, RGB crap software, razer trash, armoury crate toiletware, ... NVCleanStall 552.44 driver; Disable Telemetry, disabled NVIDIA HD Audio Device sleep timer, enable Msg Sig Interrupts (default, High Priority) BIOS, Disable PCIe Native Power Management & ASPM, Enable Resizeable BAR, power limits set to Intel spec for 13700K Windows 10: Disabled hardware accelerated GPU scheduling, Disable PCIe link Power Management, TDR delay to 15seconds, no fast start on boot NVCPL: Neg Load Bias Allow, Prefer Max Performance NOTE: Have not tried the more controversial settings such as turning off C-State in BIOS Power Supply: MSI MPG A1000G PCIE5 (12VHPWR) GPU: ASUS TUF RTX 4090 GAMING w/ latest (23-2-22) VGA Bios. I use the anti-sag adjustable support brace (although a stupid design by asus) to help support the card and (hopefully) avoid slot contact issues that might lead to the behaviour i am experiencing. AC Power: I don't use my UPS as it is only 900Watt, instead using a high quality monster power surge protector. Not sure how sensitive the MSI power supply is to voltage variations (while under higher than normal load) in wall power? I do, of course, actively profile and log all relevant sensors via HWINFO and i use the Remi Mercier's FanControl (github) for all heat mgt. Nothing recorded is ever out of temp, voltage, etc bounds for any measured component when the black screen occurs At my wits end with this and truly hoping i don't have to RMA my 4090 again.
