[2020] How many FPS?

Hate to be the bearer of bad news here, but you're technically below the minspec here. Definitely going to see sub 30 FPS.

From what I can find online I think this card supports Shader Model 4.0 (required by VALORANT) if you have the latest drivers installed.

The game MAY run but it's going to be heavily GPU limited. We don't test this spec internally so even if it runs on launch we won't guarantee future patches will continue to support it.

The CPU is also only 1.8Ghz instead of the 3.0 Ghz we recommend.

I think you'll have a really hard time unfortunately.

In terms of things you can do to try and make it better. You should be sure your laptop has two memory sticks in it to make use of the increased memory bandwidth. 2x2GB is going to outperform 1x4GB by quite a bit. If you can find a reseller you might be able to find a stick for cheap ~$5. This is especially true for players using integrated chipsets.
