Yeah, a 2080 should be more than capable of handling a game like that, badly optimized or not. I've seen people report running the game much better with way worse cards.

However all the people I see complaining here of terrible performance don't mention which CPU they have, when it was already the bottleneck in C:S 1... And the kind of people who don't think the CPU is relevant information probably aren't the kind to use a modern, top-of-the-line CPU.

I'll still wait until the patches roll in before buying it, but I'm also not going to trust complaints from players who don't even know which CPU they are using when playing a CPU-bound game.
