I cannot say for sure but I believe that your "Built Into the Motherboard" video is not up to par. If you check the PC System Requirements for NFS: Rivals you will find that your card is not on the supported list.
Here is a link to their PC system requirements listing both minimum and recommended requirements:https://help.ea.com/ca/article/need-for-speed-rivals-pc-system-requirements
Note that the minimum requirements only means that you'll be able to run the program. It doesn't mean that it will run well.
Get yourself a descent card and don't just take my advice. Do your research on video cards and learn about them or you may just end up buying a card that still won't do the job. Make sure it is an ATI or NVIDIA graphics processor and be prepared to spend some dollars. I am using an HIS HD7770 and it was around $100. It is not a top of the line card but it works fairly well and much better than the minimum requirements they state.Getting optimum performance will set you back several hundreds of dollars. You can easily spend over $1000 for a card but it is not necessary. Make sure that the card can be plugged into one of the slots on your motherboard and that the motherboard supports the type of card interface. As well, make sure you are running at least Windows 7. For some of you it may mean you're may need a newer motherboard since the new video cards may not plug into it.
The card has to generate millions of polygons every second to update the screen so therefore a slower card means poorer performance. I can't stress enough about doing your research. Of course if you don't want to do your research just buy what AE recommends.
