Note: These tweaks are mainly for pre1.1 MER. With MER 1.1 you can now choose between RGBA8, RGBA16F and RGBA32F textures. However, the tweaks under point 3 can still be applied.

Just encountered two methods to gain a few FPS (this is an understatement, I gained nearly 80 FPS in one scene, doubling the framerate) with ME. Fortunately I've noticed no* differences in quality.

1. Change the texture format from RGBA32F to RGBA8
2. Change MipLevels from 7 to 1
3. see also this post for some additonal tweaks

So it should look like this:

texture texColorHDR1 { Width = BUFFER_WIDTH; Height = BUFFER_HEIGHT; MipLevels = 1; Format = RGBA8;}; //pingtexture texColorHDR2 { Width = BUFFER_WIDTH; Height = BUFFER_HEIGHT; MipLevels = 1; Format = RGBA8;}; //pongtexture texMagicDOF { Width = BUFFER_WIDTH; Height = BUFFER_HEIGHT; MipLevels = 1; Format = RGBA8;}; #if (USE_RAYMARCH_AO == 1)texture texAO { Width = BUFFER_WIDTH; Height = BUFFER_HEIGHT; MipLevels = 1; Format = RGBA8;}; texture texAO2 { Width = BUFFER_WIDTH; Height = BUFFER_HEIGHT; MipLevels = 1; Format = RGBA8;};#endiftexture2D texDepth : DEPTH;texture texBloom1 { Width = BUFFER_WIDTH; Height = BUFFER_HEIGHT; MipLevels = 1; Format = RGBA8;};texture texBloom2 { Width = BUFFER_WIDTH/2; Height = BUFFER_HEIGHT/2; MipLevels = 1;Format = RGBA8;};texture texBloom3 { Width = BUFFER_WIDTH/4; Height = BUFFER_HEIGHT/4; MipLevels = 1;Format = RGBA8;};texture texBloom4 { Width = BUFFER_WIDTH/8; Height = BUFFER_HEIGHT/8; MipLevels = 1;Format = RGBA8;};texture texBloom5 { Width = BUFFER_WIDTH/16; Height = BUFFER_HEIGHT/16; MipLevels = 1;Format = RGBA8;};

I haven't tested Magic Dof and Raymarch AO with these values. (Edit: seems to work well)

edit:
Example Comparison (look at FPS in upper right corner)

*There may be some decrease in quality for some effects, but it's barely visible most of the time. For better dof-quality set texColorHDR2 to RGBA16 (litte fps drain). (See this post)

I just want to say this 100% worked for me too.
Master effect used to cut my framerate almost in half and now i'm seeing a 5 frame loss now which is very good.
it's only about a 6.xx percent slowdown now so it's pretty good. Maybe there are some other tweaks similar to this?

I haven't tested Raymarch AO or Magic DOF. But I don't use those for anything any ways.

Thanks.

I wouldn't speak of "destroying", just minor changes. The example scene would look totally different without the bloom.

I've tested the settings in detail with one scene (Raymarch AO and Magic Dof enabled):

Standard settings:

All textures set to MipLevel 1

texMagicDof and texAO,texAO2 set to RGBA8

All textures set to RGBA8 (so the remaining texColorHDR1 and texColorHDR2)

texColorHDR2 set to RGBA16

Conclusion (imho):
Setting texColorHDR2 to RGBA8 changes the quality of magic dof. It looks a bit more blurry and misaligned, but it works. Set to RGBA16 it looks like the original RGBA32F, but with more fps of course.
All other settings have no impact on the image (at least for this scene).

Thanks for the info.

With a R7 260x 2GB i couldn´t use the Master Effects on modern games due the loss of huge performance, even if all of the effects were turned off. I have made some testing with this trick and the performance improved vastly. I dont really care if DoF or AO looks sightly worse, the huge performance gain is enough for me to use it now.

Many thanks

I did a quick test on this again with Dawn of War (Effects used: filmic pass, reinhard linear, sharpen; the values in parentheses are with extra bloom,ao,dof):
MipLevel 7: 258 fps (47 fps)
MipLevel 1: 400 fps (53 fps)

So it definitely has an impact on the framerate. Maybe there are other reasons why it doesn't have an influence for you.

I was to able to get even more fps out of ME (ca. 5%). Essentially we abandon those HDR samplers with the corresponding EmptyHDR passes. Afaik there is no visible quality loss.
Since I don't know if Marty would approve this, instead of uploading a tweaked Reshade.fx I simply lay out the changes I made.

Steps (for replacing i suggest the find/replace functionality of your editor):
-delete the two "texture texColorHDR* {...};" declarations
-delete the two "sampler SamplerColorHDR* {...};" declarations
-replace "texColorHDR1", "texColorHDR2" with "texColor"
-replace "SamplerColorLDR","SamplerColorHDR1","SamplerColorHDR2" with "SamplerColor"
-replace "RenderTarget = texColor;" with "" (aka Nothing)
-delete all the "EmptyHDR*{...}" passes in the techniques section
-optional (no fps gain, just tidying): delete unnecessary functions: "EmptyPassHDR*{...}"

Additionally you could merge some of the passes (I've done this with a config where I use only few effects), but the performance gain would be marginal. More tweaking would require advanced HLSL knowledge, that I don't have yet.

edit: fixed some instructions

The fixes of this version are obsolete, I optimized the performance as much as possible without breaking anything.
There are no place filler passes anymore, no useless mipmaps, and so on.
Also some textures cannot be downgraded in their bit depth, see why in my last post on this page:

reshade.me/forum/shader-presentation/161...ial-thread?start=534

Forcing RGBA8 on the occlusion textures results in horrible artifacts.
