I'm not sure if I've made any kind of sim racing "hack" but I'm not seeing many results when searching for 'sim racing reading glasses', a £1.99 monitor/gfx upgrade, to me as previously a non-glasses wearer anyway. I'm no eye expert and this affects both eyes so may need caution, but I feel it's a really cheap and easy way to get much more road surface to play with if a bigger/sharper screen isn't an option right now.
B&M and most supermarkets I think sell them for a couple quid, I opted for +2.00 as I've just been prescribed glasses to wear when reading after a visit to SpecSavers at 42. I bought a cheap pair from them as their designer ones looked no better, including some special glass (+£35) for £50, but going by the new cheap one's I'd hazard a guess my prescribed ones are maybe +1.25 or +1.50 (B&M sell those strengths and 2.5, 3, 3.5 etc but trying high ones in there just blurred things for me - there's a test card and mirror in stores but I could read it all so maybe don't need these - but they make everything close bigger so got them - they blur everything further away, so not for use while moving in the real world).
For racing I sit in front of a 32" 4k hdr screen behind my wheel (maybe 6 inches behind) where I can just touch it with my fingerprints if I lean forward a bit (I'm 5"10 for reference) but the cheap +2.00 appear to add 2-3 inches at each corner when peering over the top of the glasses and back, so maybe like using a 38" screen now, although it's hard to describe it's just more immersive and the scale of everything feels so much more realistic.
I'd previously tried putting my screen directly behind the wheel where I'd nearly hit it with my knuckles, but the graphics didn't look right at all and I could see all the imperfections - I've no idea how this making it bigger just works, maybe my eyes? I've always felt it looked better on a TV further away which might make sense as I have 20/20 vision for distant stuff SpecSavers optician said. I asked if I should use my prescribed glasses for watching TV but she said no, my TV is at the end of my bed though and looks fine with them so not sure why not, maybe a risk?
Phones and Laptops also benefit from the reading glasses/my prescription ones, I generally watch YouTube at 4K although my screen is only 1800p (managed to get an affordable 15" OLED HDR one) and definitely notice the difference stepping up from 1440p on it before I went to get an eye test, making me think I must be fine. The reason i went was at night time I noticed my phone becoming harder to read, apparently it's tired eyes. I also noticed light sensitivity sometimes but they never explained that. Also asked about yellow banding in the whites but that's UV from the sun they told me, rather than too much screen time.
If anyone is able to confirm any of this for racing it could be useful for others, or let me know if there's stuff here I shouldn't be doing.
So far I've tested on WRC and DR2.0 which both benefit, and WRC9 was fine, I thought it'd highlight the imperfections but it somehow improves everything. ACC is brilliant too, but Forza Motorsport is hit and miss, some things look great like cars and crowd but other stuff seems to lack detail (I'm on Xbox so PC users might be fine - almost feel like I have a Series X 'Pro' now). I just got V-Rally 4 on sale but it's not improved, maybe took shaky or too traditional GFX, similar for Sebastien Loeb rally with older graphics, looks better without. GTA V with RT on Xbox I really like the look of normally, but these did nothing really for it in third person driving mode.
