Quick Answer
Yes. The RTX 5090 lands 120-180fps in Cities Skylines 2 at 1440p, so the only real question is whether you want that headroom for future titles rather than this one. Cities: Skylines II is brutally CPU- and simulation-bound; large cities drop frame rate regardless of GPU.
The verdict in detail
Maxed out at 1440p, Cities Skylines 2 lands 120-180fps on the RTX 5090, leaving large frame-rate and detail headroom.
Cities Skylines 2 is one of the heavier titles around, which is exactly where the RTX 5090 earns its place. At 1440p it stays GPU-bound, and features like DLSS and frame generation turn a demanding maxed preset into a smooth, high-refresh experience.
Is the RTX 5090 the sensible buy for this?
Honestly, for Cities Skylines 2 alone it is overkill. The RTX 5090 is a flagship card priced as one, and a far cheaper RTX 5070 or 5080 already maxes this title at 1440p. Buy the 5090 only if you want a true 4K, path-tracing-ready rig that will stay maxed across the most demanding releases for years. If Cities Skylines 2 is your main game, put the saving toward a high-refresh monitor and a faster CPU instead.
What it means for SA buyers
The RTX 5090 is stocked locally at Evetech, so you skip import hassle and get local warranty support. Pair it with a Ryzen 7 9800X3D, 32GB of DDR5-6000 and at least a 1000W 80 Plus Gold PSU to feed it cleanly. For Cities Skylines 2 specifically, a mid-tier card saves enough rand to fund the rest of a quiet, well-cooled build.
FAQ
Will the RTX 5090 be bottlenecked in Cities Skylines 2 at 1440p?
Even at 1440p the 5090 stays GPU-bound here, so a capable CPU avoids stutter in busy scenes. Pair it with a Ryzen 7 9800X3D so the card is never the part holding you back.
Do I need DLSS or frame generation for Cities Skylines 2 at 1440p?
Yes for the smoothest experience at maxed settings; DLSS Quality plus frame generation gives the cleanest result here.
What monitor should I pair with the RTX 5090 for Cities Skylines 2?
Match the card to a high-refresh panel: a 240Hz 1440p or a 144Hz+ 4K display lets you actually use the frames the 5090 produces in Cities Skylines 2.
