I see the logic. Gaming has traditionally driven significant technology improvements and that tech can easily be militarized. (Oh, not to mention that it has the potential to be a massive propaganda tool for teenagers.)
It might be too little too late though. While China may help Russia with chip development, they are still going to be years behind the curve. (Russia is only planning on 28nm tech by 2030. Improvements will come, but it's not going to be fast.)
If they want to succeed, they actually need to push all of their cash into it and not let it get sucked away by corruption. Given that their wunderwaffe showing in Ukraine (T-14, BMP-T, SU-57, etc.) has been extremely poor, I doubt that any new silicone is on the horizon.
