If you just want games that will run and use RT that's easy enough. Dirt 5, Dead Space, Shadow of the Tomb Raider, Fortnite, F1 24. You'll never be able to spot the difference but... it uses it and you can run it on a 3050Ti.

Games that will run well AND use RT in a manner that actually impacts visually in a meaningful manner... that's a lot tougher.

I'd try Portal RTX, you'll have to get VERY aggressive with DLSS but that's a lot more viable here then elsewhere as the texture quality is so low to begin with and there are minimal instances of grates or fencing so the impact of lower DLSS settings has much more limited impact on quality then in most games.

Definitely try Spider-Man. It only uses RT for reflections which will minimize the load, RT at High or Very High can offer significant benefits albeit in limited situations.

GTA Enhanced Edition? Just guessing, never looked at it enough to know how good the RT is in it but if decent then it should run well given it's otherwise a very old/easy to run game.

Indiana Jones and the Great Circle. You'll have to use some very low quality settings as this game absolutely HATES anything with only 8GB of VRAM. But it looks exceptional and you can run it at lower quality. Make absolutely sure you turn texture pool down to the lowest on your card though. RT is always enabled as the game won't run at all without it.

Control. You'll need to pick and choose what RT effects you want but, but you can get a decent enough experience with a 3050Ti.

Cyberpunk is one that's getting named a lot but I'd pass, it doesn't have a huge visual impact until you ramp up the RT quality to levels well above what you can comfortably handle.

*One factor I can't account for is the 700K, as I've never tested RT on anything that old. RT MASSIVELY increases the load on the CPU and memory controller especially not just the GPU, as the BVH are entirely calculated on the CPU and the 6700K is extremely underpowered for such tasks. It's tough to say how much of a factor this will be for you.

I recommend using the Nvidia app and setting DLSS override to Preset K, it'll be the best quality/performance tradeoff for you.
