can i use my integrated and amd graphics card at the same time

Solution

Virtu is a gimmick which is why it was only around for SB and most dropped it with IB when people found out exactly how it worked. The intel igpu does no graphics processing, it only sorts what the dgpu processes. In most cases any fps increase is only above the monitors refresh rate because the igpu just tells the dgpu to not process any graphics but these duplicate frames still count towards the fps counter. This is useless and the process increases input lag. The times it happens below is an issue since it also causes stuttering and as mentioned...
No, origin PC notebooks did one time but now nothing does what you ask.

It would be great however, because I saw a 10+fps increase on the benchmarks of that origin laptop that could use igpu and dgpu together (intel gpu and NVidia gpu) with Lucid.

Now, you can use multiple monitors with both igpu and gpu together, if that is also what your looking for.
