BOOSTED MEDIA SIM RACING PC EXPLAINED - How We Run Triple 4K Screens!

One of the most common questions we get asked is "How do you run triple 4K screens with such high-quality graphics and high frame rates?", so today I'm going to give you a behind the scenes look at the PC responsible for running our sim rig, what components we chose and why, then take you through the performance in detail.

As a complete PC hardware and software nerd coming to your channel for sim stuff, I am continually impressed with your knowledge of PC hardware and software configs.

[arr]

Thanks for share it! It's nice to hear that I'm not the only one who discard amd at the time to do something seriously where stability/reliability is priority over high values on unreal benchmarks and youtubers honest opinions.

ASUS also tend to use higher quality components, better component choice. Like some brands substitute capacitors on the back of the CPU for a couple big ones, but ASUS use up to 20-30 individual smaller capacitors.

Also worth mentioning, you really want an individual power cable for each input of your GPU from the PSU. If you see one cable with 2 connectors on it and think "yeah I'll use this because it will look cleaner too rather than 2 cables" then you should expect problems. The 3090 has 3 inputs, so you should use a PSU with 3 individual power outputs, splitters are out of the question.

Completely with you on Asus, I've used their motherboards since at least Pentium 3 days and I've given almost all of them away working to friends kids to play with at the end of their useful life. I think my Asus P6T-Delux gave up not so long ago (though tbh it could be something else but i'm short on 12 year old parts to swap out and test it with!). Also love those Corsair PSUs, nice to have monitoring in Windows with its control app, power the PC with a UPS and you get the readings going in at AC and the readings on the DC out from the PSU and you've got all the data you could ever need.

yep thanks for the vid..i will be running pretty much the same pc but smaller screen and VR at times...all i know is there are so many tweeks and adjustments and math and, well it gets a bit daunting and overwhelming, im not a tech guy just a mellow sim hobbyist..so vids like this really help me understand the workings a lot better so thanks...hard to find sim build orientated stuff.. tons on gaming but i don't game only sim...so any content that helps us noobs and untechy guys really helps...cheers mate

12th Gen 100% worth it. I am running a 12700k on Windows 10 and do not see the point in Windows 11 as 10 is handling it perfectly. That said, I have only been running iRacing since upgrading and am seeing up to 9 parked cores that are just sitting at 0% along with 30-40% on my 4 E Cores (running Racelabs, Trading paint, Mu for telemetry, Discord, VRS tool, Afterburner, HWmonitor, and google drive as the main apps in the background).

[PhilDiasPJD]

Great presentation as always Will. It did make me laugh the fact that you say you are bottlenecked by your 3090. 🤣 Here's me sitting here with my 1050ti 🤣

[costafilh]

Best way is to get factory waterblocked cards and use external water cooling with quick disconnects.

[MostlyElectrolytes]

I'm running a FTW3 Hybrid 3090. Had to swap the PSU out because of transient spikes. Its a beast, but there is no headroom for OC'ing. I actually did a custom power curve and undervolted it and found that it boosts better. Not really a massive uplift, but it does keep temps down even lower.

[Armin_]

You definitely don't want a GPU to fail at this point. 😅 Lucky that you got another 3090. 👌

[MsTheCops]

Hi Will; Another great video ...you're the King of Instruction. I apologize for the lengthy question but I need some advice. If you remember me ...I'm the old guy from Canada who tried to emulate your system ...on a smaller scale (budget) ...lol. I've followed all your instructions & tweaks like the Windows 10 "Ultimate Performance" settings ...but my FPS sucks!!!!
I've reached the limit for upgrades with my PC I feel. I don't see the extra value in the 3090 so I'm sticking with my 3080. The weak link in my system are my three 4 K displays (43 inches).
They were cheap but looked dang good on display at the Electronics outlet ...so I bought them. They are TV's with a 60 Hz refresh rate. I didn't see that as an issue as I didn't expect the GPU to handle much beyond that ...& it DOESN'T! The resolution in Nvidia's control panel is 12288 x 2160 ...I have the refresh rate set to 60Hz ...however; on many Sims like ACC I seldom see anything above 45Hz. I'm running the 10900KF ...as you were & I also over clock to 5.2. & my temps stay down around 50 Celsius. I use Fusion software ...in an Alienware system.
How in heck do you run those monster displays @240 Hz????!!!! Our systems are nearly identical.
Also ...how did you adjust the stretched skewing on your side monitors?
& I've upgraded to Load Cell pedals ...they are FANTASTIC! Thanks again for all the help Will.

[kbkyt]

Thanks for that, Will! Been wondering about the primary PC you’re running ever since I started watching your vids a couple months ago!

[YayDanMan]

Ooh, future review into if the 12th gen architecture has a benefit sounds super neat! If the E cores are a success that would be quite fascinating, given I’ve yet to see any conclusive evidence they’re much help in gaming situations and that could be quite the game-changer for however long it takes AMD to respond one would hope 😅

[ukrainiantym]

Hey Will. Thanks for the info. ACC now had dlss with new update. Hopefully that helps a ton with fps.

[dcandelarioch]

Could someone tell me how to connect three 4k 144hz monitors at the same time to a 4090? On YouTube there are many videos where they show setups with 4k triples at 144hz, so there must be some way to do it, but no one says how to connect them. There is a limitation on the 4090 and only two monitors can be activated with DSC at a time. I'm trying triple 4k for simracing, but I'm about to give up.

I have got 4090 zotac and tripple Asus rog pg27uqr.

Does the 4090 ROG strix allow these 3 monitors to be connected?

[jdmallia]

I really enjoy your videos! I'm more of a sim racer than a computer guy, and I usually struggle with the latter. I heard you mention resolution scaling a few times. I only use iracing, and I run triple 27 144hz screens, and I am always looking for a little performance. When you scale down the resolution, are you doing it in the iracing graphics config, windows display, or nvidia control panel, or all? I scaled iracing's recommended resolution down to the next lowest available option, but didn't change anything else. Is this the right way to go about getting more performance, or am I doing the right thing? Thanks for making this video!

[mervyoung]

Great video. I'm surprised you're running a RTX 3090 for three 4K displays. I would have thought you'd be running a 4090? Or have you upgraded to a 4090 since this video?

[TheBuzzorca]

Don’t you use fidelity fx upscaling in assetto corsa content manager for an extra few frames it works for nvidia cards too

[Rice_Cake_]

great explanation, thanks for making this. My friend's PC is having a problem that sounds identical to your power supply problem. Do you have a video that dives deeper into how you diagnosed this?

If no deep dive video exists, could you tell me how often your pc was rebooting? Did you find it would sometimes happen even when the GPU shouldn't be maxed out (i.e. not many effects happening in game)? Did you find any other solutions, such as turning down graphics settings? Thanks in advance!

[andreaiachini]

ACC is very demanding, but once you find the right setting it is very unlikely you have frame drops. It is the only upside of this game. For example with an old system (I have i7 6700 and 1080) I found a setting for 60 FPS in all climatic conditions. The benchmark was obviously night and monsoon. Once I got the 60 fps there, it is very solid and nothing can move me from that 60 fps mark I set for my system. Ironically I have more struggle with AC in starting grid for example, where I can have huge FPS drops (but with AC I usually average a lot more, I am almost all the time over 144). Anyway the real struggle for ACC is to have solid very high FPS. If you want to run 144 fps on a 144hz screen, for example. Well, in that situation you will struggle for sure. To say it all, it is possible only in single screen. With multiple screen you can almost forget it, also in 1080p.
