Paging Kikz to the thread......

All that looks fine. What is your internet connection?

You should be fine dude.

I used to play iRacing on a much older rig and it worked just fine.

Have you played iRacing before?
Look around for a promo before committing to it in a huge way (this PC will allow you to do a lot of things with it that aren’t iRacing of course)

I really enjoyed my iRacing experience (I didn’t sub long term, but used a few 3 month promos to get some time in the sim) but there are some limitations you should be aware of.

#1 it’s not ‘a game’. There are rules, and quite the learning curve between this and other racing games. The handling model in this has a high level of fidelity, and there are tutorials for ‘how to shave tenths of a second off your time’ (trail braking in the mx-5 cup cars was massive for me)

#2 as a Sim, there are some aspects of it that you can’t get enough feedback from the game or peripherals.
Buy a decent wheel (you don’t need to look any further than a basic Logitech FFB wheel) but understand that when you lock the tyres under heavy braking, or spin the wheels by ‘using too much foot’ you won’t get any physical cues other than sound effects from the game.

It can be frustrating, but it can also be very rewarding at times too.

Look at peripherals, as I said a Logitech FFB wheel is a good start (G29/G920 and the H-pattern shifter, or I’m still using a G25 (though a G-27 works too)), a track IR is an excellent peripheral if you don’t want to consider VR HMDs. I see you have two monitors... can you set up a third?
Setting up display linking so you have one continuous display area is pretty fantastic, you can then just look left or right to see if there’s a car beside you (though a TrackIR, or HMD are probably a better option)
