hallo wy is the gtx 750 ti not supportet in doom and can i play it with the 750???

Play what?

doom

Doom should be quite heavy, so DOOM on older and not powerful enough GPUs will be a problem.

You can see the chart below:

It should not be too hard to jump up a tier to the 780. you have almost a month for it.

i just buyed my card and im not gonna by a new one only for doom than i not gonna buy doom i can play the division tom clansy al in high settings so np and im gonns buy overwatch blizzard game than i hope the lower the req for doom wi help to get player alot of ppl got a gtx 750 ti:)

The 750ti should technically run doom 4 but you will be buying the game at your own risk as performance could be unplayable. People run Fallout 4 with below spec hardware (there are limits).

oh wel np there ar planty more shooters for the gtx 750 ti overwatch is coming out:) i play doom when i buy a new card over 2 years or mayby the lower req u never know
