Hey everyone! I just bought a Lenovo Legion with an RTX 5070 8GB GPU, an Intel i7-13650HX CPU, and 24GB of DDR5 RAM. Right now, I'm using two 1080p monitors and playing games like Overwatch, Witcher 3, and Cyberpunk. I'm considering switching to a dual 1440p monitor setup and have a few questions.
1. How much performance drop should I expect? Currently, I get around 120fps in Witcher 3 at 1080p. If I switch to 1440p, will my fps drop to around 70-80 as I've heard? That seems like a 30-40% decrease.
2. I watched a video suggesting that newer GPUs are built for higher resolutions, and that playing at 1080p might be bottlenecking my GPU. Is that true? I felt it was smoother playing Witcher 3 at 1440p on my laptop, but is that just a placebo?
3. I have one monitor that's 200Hz and the other 100Hz. When I connect the 200Hz monitor via HDMI to USB-C, it caps at 60Hz or 100Hz. Is that due to the cable? I've heard DisplayPort to USB-C cables perform better. Would this one I found be suitable?
4. Lastly, regarding VRAM, my GPU has 8GB. Does it mainly relate to texture quality? When I max out settings but lower textures, I get better fps. Is VRAM only about textures, or does it affect other factors too?
Thanks for any insights!

When you bump up to 1440p, you can expect roughly a 30-50% hit on performance due to the increased pixel count—1440p has about 33% more pixels than 1080p! It's definitely true that playing at 1080p could bottleneck your GPU's capabilities. Higher resolutions let the GPU do more work, taking some load off the CPU. As for your cable, you're right: HDMI can limit your refresh rates. To hit 200Hz at 1440p, you'll need an HDMI 2.1 cable or a good DisplayPort to USB-C cable!
Yeah, if you're running high settings, lowering texture quality will generally boost your fps because those high-res textures take up more VRAM. So, it's smart to keep texture quality balanced with your other settings! And as for the monitors, it really depends on the cable and the capabilities of your laptop's ports too. If they can't support the higher refresh rates, it’ll cap you no matter what. Try getting a quality DisplayPort cable for better results!
You're spot on about VRAM! Texture quality and shadow details consume a lot of VRAM space, so lowering those can help you stay under that 8GB limit, especially in VRAM-hungry games. If you're facing issues, try searching for optimized settings specific to your game for better performance tips!
So is it true that increasing resolution drastically affects performance? How does that work?
