I know people are trying to help the user dareESP, But could you try and give the right information.
Support for the GTX 750 Ti is not ending in October as it's NOT a Kepler base GPU
like the rest of the 700/600 series, it's based on the Maxwell GM107 GPU that succeeded Kepler.
The 900 series is also Based on Maxwell 2.0
Critical security updates will be available to Kepler-700/600 series GPUs through September 2024.
Nvidia Specifications show GTX 750Ti as Microsoft DirectX 11.2 API
DDR3 Memory Speed of 1066Mhz = 2133Mhz
DDR4 Memory Speed of 1200Mhz = 2400Mhz
Because DDR memory reads and writes at the same time they sell it by
the effective speed X2 of the actual speed.
Below is a better way to explain it!
The name "double data rate" refers to the fact that a DDR SDRAM with a certain clock frequency achieves nearly twice the bandwidth of a SDR SDRAM running at the same clock frequency, due to double pumping
@dareESP
I would have at a guess your poor performance is your GTX 750Ti 2GB Video
buffer, Game Guru Max needs 4GB of video memory these days.
Your CPU is a Great Chip, But has slow single core mark of about 1400, Game Guru
works best with High single core CPU's of 2000 marks and above. as it won't use all 6 cores.
(I don't have MAX maybe it uses more cores now than GGC did?)
Just to give people an idea of how CPUs have move on
Your CPU Mark of = 6116 with a single core score of 1397
i3 10100f Mark of = 8781 with a single core score of 2611
4 cores and 8 threads COST = £80.00
With a new GPU say a 1050ti 4GB or better still AMD RX 570 4 GB the rest of your computer should be up to running GG MAX.
