I really don't understand how Intels drivers for Alchemist are so flawed, they have integrated GPUs that run esports titles at 100+fps.
It seemed to me scaling the existing architecture to have more processing and bandwidth should have yielded a very competitive GPU while reusing their existing talent pool.
Instead we end up with a very buggy, very specialized (needs resizable bar?, DX12 works well but not other runtimes?) that aren't required today for Intel graphics.
- wtallis 4y agoOne pattern that has emerged is many of the performance problems come from VRAM no longer being carved out of main system RAM. The drivers now have to be careful about which pool of memory they allocate from, and for CPU access to VRAM without ReBAR the access patterns matter a lot more than they used to.
- wmf 4y agoIt's amazing that fixing that one thing takes over three years.
- terafo 4y agoDX12 works well cause it was designed to make driver development easier. Last gen APIs required specific optimizations in drivers for every single game in order for it to run well. And as far as I heard the problem isn't in drivers, problem is in hardware scheduler that have some kind of limitations that become more apparent with scale. It might be impossible to fix this without retape.
