Why do you think so? The deferred renderer pays a higher “up front” cost, in order to pay less per light you use. The 750 is so old, it may have trouble doing the final compositing stage where all the different buffers (normal, color, depth, light contribution, etc) are finally shaded to an output color, and that may be causing your frame rate.
Anyway, another thing that could be going on is, perhaps you’re using the Intel built-in GPU instead of the 750? That’s something to look into.
When it comes to making the viewport smaller, perhaps the editor re-renders the entire GUI every frame; if that’s the case, then the frame rate should go up if you resize the editor window to me much smaller than the screen; i e frame rate should be linearly proportional to number of pixels covered by the editor window. In that case, you are totally fill rate limited, and only a better GPU or smaller window will solve it.
Here are some rough measurements (with the default level):
ue 4.15, no hiDPI mode, interface full screen, viewport 1064x472 (out of 1440x900): 60 fps (capped)
ue 4.15, hiDPI, interface full screen, viewport 2208x944 (i.e. same as before, only retina, so 4x pixels) 20 fps
ue 4.15, hiDPI, interface full screen, viewport 1064x472 (i.e. viewport reduced to 1/4) 37 fps
ue 4.15, hiDPI, interface 1/4 of the screen, viewport scaled as to reproduce initial situation: 60 fps
So sure, fill-rate limited. However in case 3), the scene is as costly to render as in 1, so the drop in fps comes from rendering the rest of UI at 4x resolution (compared to 1). Perhaps that can be improved by optimising UI rendering code as for example, in Unity, hiDPI rendering is not that much costly, even with deferred rendering.
p.s. pretty sure I am not using the integrated gpu because of the fan noise I hear
From UE4, in this post:-
We are targeting a week or two from now, once is back from GDC, we’ve addressed the most important issues, and have fully quality-tested the update.
And it was typed in 3rd March… so I guess the latest date would be 17 March or so…
Soooo since VS2017 is out now, when can we expect UnrealVS supporting VS2017 RTM? Because UnrealVS does not work under VS2017 RTM, at least not for me :S
Subjectively it is faster, though I haven’t made any specific tests. It also depends on what features you installed. I only have C# and C++ tools installed, so its quite slim.
Recently typing LERP in the material editor brings up Lerp multiple Float 2 as first guess and not Linear Interpolation. It’s a small thing but a bit annoying. Would it be possible to change it back?
I update my blueprint project to the new version, I currently use arrays to save actors, my project makes use of these arrays to create maps on the scene according to a maximum of maps per scene … so I’m deleting and adding maps dynamically according to certain conditions. I made the change of the arrays by TMaps, but after some time of execution of my application, the engine freezes, without throwing any error, it simply freezes. I think that the TMaps do not have any validation in the handling of Ids, Everything works before id 50, since when in the TMap I have the values 45,46,47,48,49 with a maximum of 5 maps per scene, I delete the 45 and I try to add the 50, do not add it and freeze the engine.
I just recently made a bug report about either this exact problem or something very similar to it.
I get the feeling that it is the result of removing many elements at once, followed by adding a new element.
(scroll down to my reply for a simple repro example)
Let the crashing begin, I have had this problem since version 4.14, can someone please for the love of god look into this, ive did the whole disable realtime thumbnails thing, helped maybe a little. Here is a video of it happening in real time, you don’t have to watch the whole video but watch just a few minutes of it and you can see the repro steps.
