Racing sims are traditionally not the most taxing of things depending on certain factors so I wouldn't actually put this past being a reality but who has the money for an 8K screen? Those that do, would likely have the money to have the best of breed that money can buy PC anyway.

You can get 8k Samsung’s for near £2k now. By this time next year I imagine they will be widely available and well under 2k. LG is set to release the new 8k OLEDS early next year too. Not everyone who buys a super high end tv is interested in PC gaming.
