Lc0.28 released

Multi stream on my 2070 reduces NPS. Sure this is a good switch to go ?!

0.28.0 removed from hard drive now.

Which nets does each use? If you are using default net, nps drop is expected, since it changed from T70 to T75 (a bigger net)

For better or for worse there are great many configuration options for Lc0.
Which options are best depends on the GPU (or CPU) hardware (and drivers and libraries), the net size, time controls and Lc0 version.
The changes with v28 may be slower or faster in nps depending on a particular configuration.
However, there are search changes, so nps speed is not as important as actual playing strength.
That said, overall the 1650 is a pretty weak GPU for Lc0.

Even for SF, nps in the NNUE era does not mean much relative to strength.

So pretty much you can almost always place a GPU into any card in any standard ATX, mATX, mini-iTX or other type of boards. built after 1996. And PCI express(the slot where the GPU will go, and many other devices can go too) is fully backward compatible, if you have a PCI express 1.1 slot you can still use PCI e 2.0 or 3.0 card, only that it will run at 1.1 and vice versa. Therefore, most motherboard will be compatible with most GPU and the only time you should have an issue is with a HP prebuilt system that has the chipset cooler in such a way that even small cards like 7790 couldn't be installed, not a compatability issue by the way, a riser cable would just work fine but its just that so again just check out the manuals.

Are you confusing PCI with PCI Express? Because in 1996 even AGP wasn't available....

What I meant to say is that after 1996 any Motherboard with PCI or PCI express are fully compatible with any standard ATX, mATX, mini-iTX or other type of motherboards and if you have a PCI express 1.1 slot you can still use PCI e 2.0 or 3.0 card, only that it will run at 1.1 and vice versa. Therefore, most motherboard will be compatible with most GPU and the only time you should have an issue is with a HP prebuilt system.
