Interesting link for you - https://www.notebookcheck.net/AMD-Radeon-R8-M445DX-Dual-Graphics-Benchmarks-and-Specs.169457.0.html
"The AMD Radeon R8 M445DX is a Dual Graphics combination of the integrated Radeon R5 (Bristol Ridge, e.g. in the A10-9600P) and a dedicated Radeon R7 M440 graphics card... In our gaming tests, the performance of the Dual Graphics combination depends on the driver support. Except 3DMark benchmarks however, we saw nearly no game that could profit from the Crossfire combination with the launch drivers. Currently, buyers should only see the R8 M445DX as a single R7 M440."
So reading that it appears there is no Radeon R8 M445DX "chip" as such. It is just AMD's name for a combination of the iGPU contained in Bristol Ridge CPU's, and the R7 M440 discrete GPU (which is apparently identical in spec to the R7 M340).
Looking into it further, regarding the R7 M440 dedicated GPU performance - https://www.notebookcheck.net/AMD-Radeon-R7-M440-Benchmarks-and-Specs.169455.0.html
"The gaming performance is comparable to the Radeon R7 M340 (as it has the same specs) or an Nvidia GeForce 920M. Therefore, demanding games of 2015 and 2016 may only be playable in the lowest detail settings and low resolutions."
I know GTA IV is an old game now, but IIRC the PC version was notorious for being badly optimised, even struggling on PC's with much higher spec's than the "recommended". See - http://www.tomshardware.co.uk/answers/id-2827405/gta-low-performance-high-end.html
I would recommend allowing Windows updates. There are some critical security patches issued from time to time and if you're on the internet with an unpatched machine, it's asking for trouble. As far as I know, there's nothing to stop you manually installing the AMD drivers downloaded directly from their website. I've read however that the very latest one, the "Adrenaline Edition" may be one to skip if you still play DirectX 9 games. Apparently it breaks (some of) them - https://www.pcworld.com/article/3245388/components-graphics/amd-fix-radeon-software-adrenalin-bug-dx9-games.html
