I had a lot of problems with accurate frame timing when the optimization was on, but this was mainly due to a slightly different form of Windows message pump I was using. Yesterday evening I tested again my program with threaded optimisation on, and I didn't get the incredible framerate hit that I had noticed a year ago, but I still get a slowdown of ~500 to 200 fps (which of course doesn't mean that much on so high framerates, I will have to make more serious tests in heavier loads). If you do something 'strange', it might interfere with these assumptions.īut you're right, NV should be more open about how the feature works and how you can optimize for it and avoid pitfalls.

In order to do so, some standard use practices have apparently been assumed by the driver devs. It also doesn't like you manually messing around with thread affinity - but again, you shouldn't do that.įrom what I gathered from NVs side, the optimization uses some internal heuristics to determine how it will multithread the parts of the driver used by your app. Having threads spinlock for a long time also seem to get it off track (but you shouldn't do that anyway). Messing around with priorities seems to have an effect. And it is extremely sensitive about how you manage multi-threading in your application, especially on multicore CPUs. I don't know why, it must use it for thread sync or something. However it is quite sensitive to things you do with the windows message pump.

I wasn't able to track the source of that one down (except for disabling threaded optimization), but it magically went away with a driver update and never came back.įrom what I can say, threaded optimization works very well. After a few hundred slow frames, the FPS would suddendly shoot up and then stay high until the engine was restarted. Even very few faces (100k or so) in the view would grind a 8800 almost to a halt. I put it back to normal, and everything was fine.įinally, I had another very weird effect on an older driver. For whatever reason (I didn't write that part of the code) that thread had slightly elevated priority.

I traced it down to a license check thread that was waking up every few seconds to check a USB dongle. It didn't happen with threaded optimization switched off. Every few seconds, the framerate would drop, and then go up again. I also got slowdowns while having a heavy physics simulation running on 3 cores, while the fourth core run the 3D engine. I realised that what I was doing wasn't explicitly supported by MS, so I reverted back to a standard pump. I had a lot of problems with accurate frame timing when the optimization was on, but this was mainly due to a slightly different form of Windows message pump I was using (due to it running in a separate thread).

However, I noticed that each time I had trouble with threaded optimization (usually slowdowns, although not as much as yours), it turned out to be my code in the end. Difficult to say, it seems to be very picky. Hope this answers all your queries, if not please do repost back.Is there somewhere a list of things to avoid when threaded optimization is enabled and that could explain the framerate going from 1000 fps to 10 fps ?

Windows Security is built-in to Windows 10 and includes an anti-virus program called Microsoft Defender Antivirus.
