Hmm, I used to have 11th gen, I thought it felt pretty good for an iGPU (at reasonable graphics settings for an iGPU).
You could check whether your system is performing well relative to others with the same chip by comparing benchmarks
Here’s some published results:
- FurMark2 - Iris XE Graphics (i7-1165G7)
- 3DMark - Intel Iris Xe Graphics G7 96EU(1x) and Intel Core i7-1165G7 (demo is free)
- PassMark - Intel Iris Xe
- glmark2 - Framework Intel Core i7-1165G7 benchmarks
(note that the i5-1135G7 has 80 execution units instead of 96, if that’s what you have).
