this is not general IV solution center, only for fusionfix related issues.

[Plokhi]

Sorry should've clarified: this only happens with FusionFix loaded. I tried different settings but it doesn't change the behaviour.

It doesn't happen at all if i remove FusionFix. DxWrapper has no effect. Other than that i only have ASI loader and Xliveless installed.

While fusion fix is working with older game versions, Its support is only aimed for latest CE version.

[Plokhi]

ah. :/ until rockstar fixed my login unfortunately i need to use the 1.0.8 downgrade.

[Plokhi]

could it have anything to do wilth tile stippling? it looks as a grid most of the time. Lowering definiton to classic seems to make it less present, but still present.

Since you mentioned you're using ThirteenAG's DXWrapper, that may be the issue. It has not been updated in quite some time and no one really uses it for GTAIV...

Instead, I'd recommend using this one: https://github.com/elishacloud/dxwrapper Or DXVK: https://github.com/sTc2201/dxvk

[Plokhi]

I use both, without ThirteenAG d3d9.dll, FusionFix wont load and without DxWrapper you linked i get stuttering. DXVK unfortunately doesn’t work on Parallels :(

[RecklessGlue540]

doesn’t work on Parallels

What do you even mean by this?

[Plokhi]

I'm running this on a Mac via Parallels virtualisation software (i know i know, but it really is playable aside the glitches).

I've broken everything somehow so i'm doing it from scratch again and i'll try this in addition https://github.com/Parallellines0451/GTAIV.EFLC.FusionShaders

[Plokhi]

reinstalled and same happens, it's making me go crazy lol

[Plokhi]

so, 1.9.6 works, but 2.0.0 immediately this start to happen. There's something changed between v1 and v2 that causes it

[Plokhi]

this is fusionfix v2.0 - everyyhing set to LOW or OFF, look at windshields mostly

[Plokhi]

it becomes much worse with "definition", but "classic" seems to make it by far the least offending.

[RecklessGlue540]

You should honestly expect issues like these on a Mac using translation software...

Classic Definition obviously makes it less visible, since it blurs the whole screen.

[Plokhi]

I mean, yeah - but there's something in FusionFix newer than 1.96 that triggers it :) since FusionFix isn't exaggerating something present in the game even running FusionFix 1.96

there also appears to be some specific areas that behave exceptionally worse than others

[Plokhi]

I removed rage_postfx.fxc from the shaders folder and the issue is gone... However, so are the windshields and all car windows :D

[Plokhi]

so i guess it's something with some shader? if i remove some other shader this doesn't happen, but i have no clue how to fix this. It's so hard to go back to non-fusionfix now lol, it looks broken

[Plokhi]

Nevermind, i just discovered the same pattern when disabling fusionfix. the only thing is it only appears from inside (i.e. taxi) and it's black and much less pronounced. So it's part of the issues outside the mod - the mod just exaggerates it.

oh well

[Plokhi]

I managed to partially fix it by replacing the rage_postfx.fxc with the original one.

I lose some stuff tho, but at least it's playable with fusionfix perks :)

[Plokhi]

So apparently i lose Bloom, DOF. (i mean, postfx,eh?), but i get better reflections and Z fighting fixes and some performance improvement when setup correctly. I keep AA and most of other stuff.

wish i was smart enough to fix postfx shader myself :)
