RAM is either you have enough or you don't. Lack of RAM will cause occasional stuttering as new assets are loaded from the disk drive on the fly. I've seen 40GB+ in use playing on highly populated servers. It will not increase FPS.

You're wasting your time/money with a 6700xt and would especially so with any FX series CPU. But have fun.

Spends thousands of dollars on upgrades and still have meh performance in VR. That's real

Let's be real, a 2060S isn't really suitable for VR post 2.5 PD 1.0, lower resolution in OXRTK possibly, no MSAA and low textures might make it playable. Adjust up from there if able.

My 6900xt runs flatscreen brilliantly the few times I've bothered.

I'll wait until the 5000 series comes out and/or hope for Vulkan improvements myself. Can't justify dumping thousands of $s into this sim and its poor performance every year considering 5 year ago I was getting decent performance out of a 1080ti when the F18 released.

If GPU is 99% loaded then it is the bottleneck. A multicore CPU will likely never read 100% outside of rendering or something like that which can fully load all of your cores/threads. ETA: Just as an example that can be CPU single thread bottlenecked. A single threaded app on a quad core CPU can be CPU limited with a CPU usage level of 25%. But if CPU limited your GPU usage would be lower. GPU at 99% is the tell really.

What settings and scenario are you getting 90fps?

I'm having trouble wrapping my head around how higher FOV and lower resolution is giving better clarity. Maybe the displays are just that much better otherwise? signed, Former Oculus Rift and current HP G1 wearer

750 watt is plenty for a 9700k and 4070ti

Good question. From the MT FAQ: What is the maximum number of threads the game can utilize? About half of P-cores are dedicated for the graphics needs. Currently the rendering pool scales up to 16 threads on P-cores (1 core = 2 threads). The other P-cores are used by the main logic thread, sound engine threads, and the auxiliary thread pool that occupy all available space. E-cores are used only by the resources streaming pool that has no limits (1 core = 1 thread). Intel E cores vs AMD L3 cache

This would be my move at this point. Alternatively if sticking with Intel - 13xxx CPU with DDR4 board and rob the DDR4 out of your current system for an upgrade on the cheap. Guessing if you have a 4090 money isn't a big concern though

I'm not sure if the DCS FPS overlay is working correctly. According to Open XR Toolkit I am GPU limited in Caucuses F-14 Free Flight. 2-3ms CPU Frametime but 10-13ms GPU. PD1.0 and rather modest graphic settings. Others in the DCS VR forum are saying they are GPU limited with 4090s also.

SSD gen won't likely make any practical difference - a few seconds off your mission load times. As for the motherboard, it just depends on how many CPU generations AM5 will see. I'd be surprised if it lasts as long as AM4 did.

Single core IPC on the 12700k is ~30% faster than 9900k. CPU frequency comparisons across generations/manufacturers hasn't been adequate for a long time.

+! This is good advice. I launch DCS from the desktop and I don't even put my headset on until I'm loaded into the cockpit.

I went with 2x32GB DDR4 on my latest build due to the following rationale: I've seen over 34GB committed memory on Georgia at War. Z690 seems to not like 4 sticks, so 2x16 now and 2x16 later may not play nice in my case. DDR4 is cheap compared to 5, and cheap in comparison to $3k that everything else cost. Possible component shortages given the world situation and inflation.

Normal behavior online for me as well

I've had over 34GB memory committed on Georgia at War, that's why my new system has 64GB DDR4 (and easier on the IMC running 2x32GB rather than going to 4x16 later). I dropped 3 grand on my PC and it is still limited by CPU or server side in multiplayer unless I throw on MSAA. This sim has terrible performance and it's hard to spend that kinda cash and still be somewhat disappointed when everything else performs wonderfully

That's how I did it for the F14 with my wife

Upgrading a motherboard is pretty much always going to require a reinstall of Windows

I would say you have your fan setup backwards. IMO you should have your front/bottom case fans as intake and your AIO fans exhausting out the top. I also prefer to have one more intake than exhaust. 12700k with a Power Color Red Devil 6900 XT here. Not sure what the reference fan curve is like, but I would adjust it to come on sooner if it has a fan stop and try lowering the voltage. Use a profile for DCS, try subtracting 50mv or so to start. Worst case you'll get artificats or system will hang.

Mostly used for flight sims and you're buying a laptop?

Make sure your your BIOS is up to date and put a 5600x or 5800x in it https://www.asrock.com/mb/AMD/B450M-HDV/index.asp

I recently upgraded from a GTX1070 to the 6900XT and it has performed great for me so far with a Reverb
