GTA BOOM has covered the most popular and most advanced graphical mods out there quite extensively - however, will they get you banned from GTA Online?
These mods allow PC users to drastically enhance the visuals of GTA V by adding extremely high resolution textures to the game, as well as new visual effects and tweaks to existing ones. The kinds of results these mods have achieved are nothing less than astounding, with the most popular ones creating a near photo-realistic graphics while playing - provided you have a rig powerful enough to run it.
Now, these graphical mods increase visual fidelity and improve special effects, but they don't affect gameplay - or do they? The question whether or now strictly visual mods are allowed in GTA Online has been one even Rockstar Support hasn't been able to answer for a good long while. Players have spoken of instances when even after a 6 response ticket was closed, the support representative still could not provide a clear answer as to whether or not its use is a bannable offense.
Some users of SweetFX have, surprisingly, gotten positive response from Rockstar.
As long as you do not use the mods to effect the online experience you will not be banned.
However, it seems Rockstar's policy has since changed, and this is likely to be a result of the prolonged crisis regarding the extremely high amount of hackers present in GTA Online. Most recently, one player reported that they got a very, very clear response from Rockstar, which is bound to quell any further discussion on the matter for good.
Unfortunately, mods of any kind are prohibited for online use. This would include graphic enhancement mods.
Another rep goes on to clarify as to the reason why.
Even a subtle change in saturation can give you an edge in visibility (eliminating glare for instance) when engaged in PVP.
Straight from the source folks - no graphics mods are allowed in GTA Online.
Have you guys been using any visual mods while playing GTA Online?
Banning graphic mods is retarded and pointless, all they do is make the game look better because right now with no mods of any kind, the game looks gross and if I'm gonna play the game I at least want it to look pleasing to my eyes, however I don't think they are banned in role play servers and they shouldn't be banned in any servers. Luckily RockstarGames don't control role play servers.
