Seeing this reminds me to say that I actually got my closed beta key for Rennsport last month, only after signing up for a chance at it a year ago and not seeing the e-mail and redeeming the key (which, BTW, it runs through the Epic Games launcher) until a few days ago. Have not gotten into an official race with it yet but in testing one of the first things I can say is that it feels basically akin to ACC lol. Runs on UE5 and it shows, has similar graphical problems as ACC that I like to pick on. E.g. temporal anti-aliasing being the default AA which causes cars at speed to have a ghosting effect and smudges dashboard numbers together, and there's a weird fast-moving film grain/dithering effect on the screen at all times which is somewhat (but not entirely) remediated by using temporal AA and/or low visual effects.
Besides complaining about Unreal graphics, another strange thing I discovered is that car setups don't actually exist yet, so you just run a default base at all times. Means stuff like the TCR cars at Daytona will quickly top out which is lame.
The input and calibration setup for the wheel and pedals looks and works in a nearly identical manner to the way it does in iRacing, which is not a bad thing but it's just kinda funny. Copied homework there a little.
There's a fair few things that are technically available in the main menu but don't have anything within or are 'Coming Soon'. There's 'Custom Contests' for custom races (obviously) but there is no apparent option to host an event and there's nothing in the server list. Time Trials are soon™, and looking under my profile tab, a 'Shop' and 'Friends' are soon™. There's also an achievements page with things listed under the categories 'Play' and 'Compete', but there are also the blank 'Create', 'Engage', and 'Collect' categories. Wonder what'll be under those.
Don't know if I have much more than that to say at the moment.. Need to actually start racing and get a feel for it lol. But overall I'm interested in seeing what becomes of all this. Very curious if there's intended to be some community/user-generated content focus judging by the current inclusion of that Orchard Road track and also a figure-eight called 8ETA both marked as community content, and the above mentioned achievement stuff.
